Question

Write
Alkane, Alkene
Alkene and Definition​

Answer 1

Answer:

Alkanes consist of only single bonds and are represented by the formula CnH2n+2. Alkenes consist of atleast one double bond and are represented by the formula CnH2n. Alkynes consist of atleast one triple bond and are represented by the formula CnH2n−2.

Answer 2

ANSWER :

(i) ALKANES :-

An Alkane is a hydrocarbon in which carbon atoms are connected by only one single covalent bond . The names if these saturated hydrocarbons end with 'ane' .

EXAMPLES :- Methane (CH₄) ,Ethane (C₂H₆)

(ii) ALKENES :-

An Alkene is a hydrocarbon in which carbon atoms are connected by double bonds . The names of Alkenes end with 'ene'

EXAMPLES :- Ethene (C₂H₄) , Propene (C₃H₆)

(iii) ALKYNES :-

An alkyne is a hydrocarbon in which carbon atoms are connected by triple bonds. The names of alkynes end with 'yne'

EXAMPLES :- Ethyne (C₂H₂ ) , Propyne (C₃H₄)

NOTE :-

Alkanes come under saturated hydrocarbons where as , Alkynes and Alkenes come under Unstaurated hydrocarbons.
