Question

write the molecular formula and structural formula of an alkene having 5 carbon atoms ​

Answer 1

Answer:

IUPAC Name 1-pentene

Molecular Formula C 5H 10

Condensed Structural Formula CH 2=CH(CH 2) 2CH 3

Melting Point (°C) –138

Boiling Point (°C) 30

Explanation:

Answer 2

Explanation:

For alkene..

If n = 5

General formula..

$C_n H_{2n}$

By using above formula. ..

put n = 5

It's pentene

$CH_3 CH CH CH_2 CH_3$

Now your alkene is =>

$C_5 H_{2 \times 5} \\ \\ \huge\boxed{ C_5 H_{10}}$
