Vedclass · Answer

(D) Carboxylic acids form dimers in the vapor phase or in non-polar solvents due to intermolecular hydrogen bonding. In this structure,two carboxylic acid molecules are linked by two hydrogen bonds. Counting the atoms involved in the ring: $1$. Carbon atom of the first carboxyl group $2$. Oxygen atom of the first carboxyl group $3$. Hydrogen atom involved in the first hydrogen bond $4$. Oxygen atom of the second carboxyl group $5$. Carbon atom of the second carboxyl group $6$. Oxygen atom of the second carboxyl group $7$. Hydrogen atom involved in the second hydrogen bond $8$. Oxygen atom of the first carboxyl group Thus,it forms an $8-$membered ring.

What sized ring is formed when two carboxylic acids form a dimeric structure through intermolecular hydrogen bonding? (Consider the hydrogen bond as a bond in the ring structure.)
