Question

When n butane is heated in the presence of alcl3/hcl it will be converted into?

Answer 1

When n butane is heated in the presence of alcl3/hcl it will be converted into: Isobutane

Explanation:

Butane

It is a member of alkane .

Its general formula CnH2n₊₂

When it is heated in presence of aluminium chloride in presence of hydrogen chloride : it forms its isomer : Isobutane .

The reaction is given as :

CH₃CH₂CH₂CH₃------------------------> CH₃CH(CH₃)CH₃

    n-butane    (Aluminium chloride /HCl)    Iso-butane

Isomerism

The phenomenon in which the compound exist in to two or more forms having same molecular formula but different structures .

The different structures are called as isomers .

In the above asked question ,the butane  in presence of aluminium chloride in presence of HCl forms isobutane .This is a rearrangement reaction   .                                                                  

Answer 2

n-butane on heating in the presence of $AlCl_3/HCl$, it will be converted into isobutane(an alkane).

• Chemical Equation is given by:
• $CH_3CH_2CH_2CH_3$ →→→→→→→→ $CH_3CH(CH_3)CH_3$
•        n-butane    $AlCl_3/HCl$             isobutane
• The product obtained is an isomer of n-butane.
• This isomer is formed when n-butane is reacted with HCl during the reaction. This step is called as Isomerization step.
• Isomer: Compounds with the same number of atoms with different structures, i.e they have the same chemical formula but different structural arrangement of atoms.
