An active methylene compound is a molecule that has a methylene group (CH2) adjacent to a carbonyl group (C=O) which can undergo nucleophilic substitution reactions. Examples include compounds like acetylacetone and malonic acid. These compounds are often used in organic synthesis to introduce new functional groups and form carbon-carbon bonds.

What is reactive methylene compounds?
The hydrogen attached to a saturated carbon atom containing strong electron withdrawing groups in acidic form reacts with base to generate carbanion .such compounds which contain acidic CH2 group are called active methylene compounds . eg:CH3-CO-CH2-COO-C2H5 (ethyl aceto acetate
What is an optically active organic compound found in peppermint?
Menthol is an optically active organic compound found in peppermint. It has a characteristic minty aroma and taste. Menthol is widely used in pharmaceuticals, food flavoring, and personal care products.
What are the UV active inactive compound?
UV active compounds are substances that absorb UV radiation and exhibit a response, such as fluorescence. UV inactive compounds do not absorb UV radiation or show any response under UV light. These distinctions are important in various applications, such as sunscreen formulation or forensics.
What is the active ingredient in fabric softener?
The active ingredient in fabric softener is typically a type of cationic surfactant, such as quaternary ammonium compounds. These surfactants help reduce static electricity, soften fabric fibers, and make clothes feel smoother.
What is prestic made from?
Prestic is a type of insecticide that contains the active ingredient fipronil. It is a chemical compound that is used to control pests such as ants and cockroaches.
Process name involved the reaction of yeast and methylene blue?
Methylene blue is a solid, odorless, dark green powder at room temperature. In water this chemical compound turns into a blue solution. When methylene blue is reacted with yeast cells it inhibits the respiration which stops the cells from using hydrogen ions to release energy.
Why is methylene blue used as an indicator of cell respiration?
Methylene blue is used as an indicator of cell respiration because it can change color depending on whether it is in its oxidized or reduced form. When cells are actively respiring, they reduce methylene blue, causing it to change from blue to colorless. This color change is used to detect the presence of active respiration in the cells.
Is the active compound in ammonia acetic acid?
No. Acetic acid is the active compound in vinegar. Ammonia is its own compound, though it is diluted in water for household use.
What is asymmetrical symmetry?
The synthesis of an optically active compound from an optically inactive compound with or without using an optically active reagent.
Explain with reason whether bus topology is active or passive?
active

Why methylene blue can act on only dead yeast cells but not on live yeast cells?
Methylene blue can act on only dead yeast cells because it is able to penetrate the cell membrane easier when the cell is dead, allowing it to enter and stain the cell. In live yeast cells, the cell membrane is intact and acts as a barrier, preventing methylene blue from entering and staining the cell.
