Question

The molecular formula of a hydrocarbon is C4H8, what would be the molecular formula and name of the next member in this homologous series?​

Answer 1

Explanation:

he molecular formula of a hydrocarbon is C4H8, what would be the molecular formula

and name of the next member in this homologous series? (1)

Answer 2

Answer:

The molecular formula of the next member in this homologous series will be $C_5H_{10}$ named Pentene.

Explanation:

Homologous series -

A homologous series is a sequence of compounds with

• same functional group
• chemical properties of a group are similar.
• The next member differs by a molecular formula of $CH_2$ and molecular mass 14u from its previous member.

Given, that hydrocarbon is $C_4H_8$

$C_4H_8 +CH_2 = C_5H_{10$

Nomenclature -

Given hydrocarbon is in the form $C_nH_{2n$ which is an alkene.

$C_5H_{10$

pent + ene = Pentene
