Question

the number of carbon atom in second member of ester​

Answer 1

Answer:

3 carbon atoms

As ester constitutes a general formula RCOOR' ( here R= H or alkyl or aryl , R' = alkyl or aryl) i.e here minimum value R = H. So the first member of ester will have 2 carbons which is HCOOCH3(formate ester). Hence second member of ester family will have 3 carbon atoms.
