Lactones are (internal) cyclic esters of hydroxy-carboxylic acids:The ester bond is betweenX-C-O--H and H-O--(C=O)-Y to formX-C-O--(C=O)-Y and H--O-H(X and Y are linked by aliphatic hydrocarbon atoms)
The macromolecules that are composed primarily of C, H, and O are lipids and carbohydrates.
Aspirin has the chemical formula C9H8O4. The Lewis structure of aspirin would involve drawing the skeletal structure of 9 carbon atoms, 8 hydrogen atoms, and 4 oxygen atoms connected by single and double bonds to satisfy the octet rule for each atom in the molecule. The central part of the structure consists of a benzene ring attached to a carboxyl group (–COOH).

Isocyanate is a compound containing O, C, H, and N.
C, N, O, H as a minimum with some others such as S
C-H-O-O-S-E
Al-H < C-H < N-H < O-H
The Lewis structure of H3COCH3 (also called dimethyl ether) consists of one oxygen atom double bonded to a carbon atom, with two methyl groups (CH3) each attached to the carbon atoms. All atoms in the molecule satisfy the octet rule and there are no formal charges present.
Carbohydrates are not proteins. Carbohydrates contain C, H, O. Proteins normally contain chains of amino acids.

propanone is a carbon compound having 5 carbon atoms. As it belongs to the ketone functional group ,it has double bond with oxygen.The electron dot structure for proppanone is as follows:: H H H H x x x x o o o o H x o C o o C o o C o o C o o C o x H o o oo o o x x x x H H ** H H * O * * *
C-H-O-O-S-E
C-H-O-K-L-A-T. You want accurate spelling? then it's C-H-O-C-O-L-A-T-E.
The macromolecules that are composed primarily of C, H, and O are lipids and carbohydrates.
The least reactive bond is the C-C bond. Single bonds between carbon atoms tend to be relatively stable compared to other bonds like C-O, O-H, or H-Cl, which are more polar or reactive due to differences in electronegativity between the atoms involved.
