Question

C5H11 is an — a) alkane, b) alkene, c) alkyne, d) alkyl group...Please tell...​

Answer 1

$\underline{\underline{\huge{\bf{\red{Answer:}}}}}$

• option (d) Alkyl is correct

$\implies\boxed{\boxed{\sf{\red{C_5H_{11} \:belongs\:to\:Alkyl}}}}$

called as : n - Pentyl

Belong to : Alkyl functional group

$\underline{\underline{\huge{\bf{\red{Explanation:}}}}}$

Alkyl functional group

• Alkyl is a functional group containing only Hydrogen and Carbon atoms arranged in a chain.

• Also, the Group Formed by removal of one hydrogen atom from an alkane molecule is called Alkyl group.

Generally represented by letter R

General formula for Alkyl group

$\red{\bigstar}\boxed{\sf{C_nH_{2n +1}}}$

( where n is the number of carbon atoms in molecule )

C₅H₁₁ belonging to Alkyl group

since,

$\sf{C_{5}H_{11} \:is\:same\:as\:C_{5}H_{(2(5)+1)}}$

that is of the form

$\sf{C_n H_{2n+1}}$

therefore,

C₅H₁₁ belongs to alkyl functional group.

$\underline{\underline{\red{\bf{Alkanes}}}}$

• Alkanes are the Saturated hydrocarbons having only single bonds between the Carbon and hydrogen atoms without any functional group.

General formula for alkanes :

$\red{\bigstar}\boxed{\sf{C_nH_{2n +2}}}$

( where n is number of carbon atoms in molecule )

$\underline{\underline{\bf{\red{Alkenes}}}}$

• Alkenes are unsaturated Hydrocarbons with at least one double bond between the Carbon atoms , without any functional group.

General formula for Alkenes :

$\red{\bigstar}\boxed{\sf{C_nH_{2n}}}$

( where n is the number of carbon atoms in molecule and n cannot be equal to 1 )

$\underline{\underline{\bf{\red{Alkynes}}}}$

• Alkynes are unsaturated hydrocarbons with at least one triple bond between the Carbon atoms , without any functional group.

General formula for Alkynes :

$\red{\bigstar}\boxed{\sf{C_nH_{2n-2}}}$

( where n is the number of carbon atoms in molecule and n cannot be equal to 1 )
