the molecular formula of a hydro carbon is c2 h2 what would be the molecular formula and name of the next member in this homologeus series
Answers
Answer:
Explanation:
(i) C

2n+2
corresponds to general formula of alkanes. Since, alkanes are saturated so this series is saturated series.
(ii) Alkanes
