Answer 1

Answer:

homologous series will be yours butane

and pentane

formula of Cn H2n+2= pentane with alkane group

Answer 2

Answer:

Molecular Formula

Propene➡C3H6

1-Butene➡Condensed structural formula

➡Don't know

No.of carbon atoms➡4

1-Pentene➡No.of CH2units = 4

Explanation:

Homologous Series

➡A series of compounds in which the same functional group substitutes for hydrogen in a carbon chain is called a homologous series.

Alkane example---

CnH2n+2

n=no.of carbon atom

Let n=2

alkane formula➡C2H6
