Answer 1

Answer:a)C6H12 b)C6H6 c)C7H4 , C5H10 , C6H12 e) C5H8 , C7H12 f)C5H8 , C6H6 , C5H10 , C7H12 , C6H12

Explanation:There are 7 general formulas out of which 3 are only applicable in this case CnH2n+2 , CnH2n , CnH2n-2

CnH2n+2 = Alkanes

CnH2n =Alkenes , Cycloaklanes

CnH2n-2 = Alkynes , Cycloalkenes , alkadiene , Spiroalkane, Bicycloalkanes

Answer 2

Answer:
