Question

How many secondary bromide isomer(s) are possible for the molecular formula C5H11Br? Plz help.

Answer 1

Answer:

eight isomers.

There are eight isomers that have molecular formula C5H11Br

Answer 2

There are 3 secondary Bromide isomers possible for the supplied molecule.

Supplied molecular formula:

$\boxed{\sf{C_{5}H_{11}Br}}$

Those isomers would be called 2° bromide isomers , only when Bromine atom will be attached to a 2° Carbon atom.

The IUPAC name of the 2° bromide isomers:

• 2-Bromopentane

• 3-Bromopentane

• 2-Bromo,3-methylbutane

The structure of the above isomers are attached in the photo.

Structural formula:

1. 2-Bromopentane

$\boxed{\sf{\implies CH3-CH2-CH2-CHBr-CH3}}$

2. 3-Bromopentane

$\boxed{\sf{\implies CH3-CH2-CHBr-CH2-CH3}}$

3. 2-Bromo,3-methylbutane

$\boxed{\sf{\implies CH3-CHBr-CH(CH3)-CH3}}$
