Question

since esters are cleaved on hydrolysis, the molecular weight of the acid derived from an ester is always lower than the molecules weight of the ester. however, esters are equally liquids while carboxylic acids are usually solids. suggest reasons for this observation and explain.

Answer 1

Step-by-step explanation:

Esters contains a double bond between carbon atom and oxygen atom while carboxylic acid lack double bond between carbon and oxygen atom.The lack of double bond in carboxylic acid make the force of interaction between carbon and oxygen strong and particles become tightly packed which make carboxylic acid solid. The presence of double bond in esters make the force of interaction weak thus they are liquid.

Answer 2

Esters  contains  a  double  bond  between  carbon  atom  and  oxygen  atom  while  carboxylic  acid  lack  double  bond  between  carbon  and oxygen atom.The  lack  of  double  bond in  carboxylic  acid  make  the  force  of  interaction between  carbon  and  oxygen  strong  and  particles  become tightly  packed  which  make  carboxylic  acid  solid.  The  presence  of  double  bond  in  esters make  the  force  of  interaction  weak  thus  they  are  liquid.
