What is more reactive an aldehyde or an acid chloride?
An acid chloride is more reactive than an aldehyde due to the presence of a more electronegative Cl atom, which is better at stabilizing the resulting anion during a nucleophilic attack. Acid chlorides are known to rapidly react with various nucleophiles, whereas aldehydes are less reactive in comparison.
Is caffeine more soluble in acetone or methylene chloride?
Caffeine is more soluble in methylene chloride than in acetone. Methylene chloride is a non-polar solvent, while caffeine is a polar compound. Polar compounds like caffeine tend to be more soluble in non-polar solvents like methylene chloride.
Is ammonium chloride soluble in ethanol?
Yes, ammonium chloride is soluble in ethanol. Ethanol is a polar solvent that can dissolve many ionic compounds, including ammonium chloride.
Why is hydrogen chloride polar?
Hydrogen chloride is polar because chlorine is more electronegative than hydrogen, creating a partial negative charge on the chlorine atom and a partial positive charge on the hydrogen atom. This unequal sharing of electrons results in a dipole moment, making the molecule polar.
Why dissolve Br2 in methylene chloride and not in water?
because water is highly polar and Br2 is non-polar so the molecules in the water are more attracted to each other. But methylene chloride is non-polar so its molecules are no more strongly attracted to other methylene chloride molecules than they are to Br2 molecules. Since all of the forces are weak, the substance can dissolve.

What is more polar methyl salicylate or salicylic acid?
salicylic acid (an acid) is more polar than methyl salicylate (an ester)
Why doesn't hydrogen-chloride dissolve in methyl-benzene?
Hydrogen chloride (HCl) is a polar molecule while toluene (methylbenzene) is nonpolar. Due to the differences in polarity, they are not able to form strong enough interactions to dissolve in each other. Hydrogen chloride is more likely to dissolve in polar solvents.
Is a methyl group more polar than a hydroxyl group?
No, a hydroxyl group is more polar than a methyl group because the hydroxyl group contains an oxygen atom, which is more electronegative than carbon. This results in a greater difference in electronegativity between the atoms in the hydroxyl group, making it more polar than a methyl group.
Is caffeine more soluble in acetone or methylene chloride?
Caffeine is more soluble in methylene chloride than in acetone. Methylene chloride is a non-polar solvent, while caffeine is a polar compound. Polar compounds like caffeine tend to be more soluble in non-polar solvents like methylene chloride.
Why is methyl bromide a polar covalent bond?
Methyl bromide is a polar covalent bond because bromine is more electronegative than carbon, leading to an unequal sharing of electrons in the bond. This results in a partial negative charge on the bromine atom and a partial positive charge on the carbon atom, creating a dipole moment in the molecule.
Is chloromethane polar or non polar molecule?
Chloromethane (CH3Cl) is a polar molecule. This is because the chlorine atom is more electronegative than the hydrogen atoms, leading to an uneven distribution of electron density within the molecule.
Is oxygen more or less polar than chloride?
Oxygen is more polar than chloride because oxygen is more electronegative than chlorine. This means that oxygen has a stronger ability to attract electrons towards itself, resulting in a more polar covalent bond compared to chlorine.
What is the mechanism of methyl orange in sodium carbonate and hydrogen chloride titration?
In the presence of sodium carbonate (base) and hydrogen chloride (acid) in a titration, methyl orange indicator changes color at the endpoint. At the beginning of the titration, the solution is basic due to the sodium carbonate, causing the methyl orange to appear yellow. As the acid is added and the solution becomes more acidic, the indicator changes to red at the endpoint when all the base has been neutralized by the acid.
Is xylene more polar than toluene?
Yes, xylene is more polar than toluene due to the presence of additional methyl groups on the aromatic ring, which increases the molecule's overall polarity.
Why is hydrogen chloride (HCl) polar?
Hydrogen chloride (HCl) is polar because chlorine is more electronegative than hydrogen, leading to an unequal sharing of electrons in the H-Cl bond. This creates a separation of charge with partial positive charge on the hydrogen atom and partial negative charge on the chlorine atom, resulting in a polar molecule.
Is ammonium chloride soluble in ethanol?
Yes, ammonium chloride is soluble in ethanol. Ethanol is a polar solvent that can dissolve many ionic compounds, including ammonium chloride.
