Answer 1

Answer #1

Molar mass of the compound = 108.2 g/mol

Molar mass of C₂H₃= 12*2+3*1= 24+3= 27 g/mol

Therefore repeating unit of C₂H₃= molar mass of compound/molar mass of C₂H₃= 108.2/27= 4

Hence molecular formula of compound= (C₂H₃)_n=(C₂H₃)₄= C₈H₁₂

Therefore correct option = (A)=C₈H₁₂

Your one thumbs up will help me lot. Thanks!
