Question

Differentiate between alkane, alkene, alkyl, and alkyne?

Answer 1

Alkane	Alkene	Alkyl	Alkyne
1. They are hydrocarbons that are joined by single bonds only, called as saturated hydrocarbons.	1. They are joined by at least one double bond between them. They are reactive in nature and are called unsaturated hydrocarbons.	1. They are the hydrocarbons that are formed when one hydrogen molecule is removed from the alkane.	1. They are unsaturated hydrocarbons that have at least one triple bond between them.
2. The general formula is CnH2n+2.	2. Their general formula (not including cyclic compounds) is CnH2n.	2. The Alkyl group is made from an alkane and its general formula is alkyl group is CnH2n+1.	2. The general formula is CnH2n-2.
3. Name of compounds will end with suffix ‘-ane’.	3. Name of compounds will end with suffix ‘-ene’.	3. Name of compounds will end with suffix ‘-yl’.	3. Name of compounds will end with suffix ‘-yne’.
4. Examples: Methane (CH4) Ethane (C2H6) etc.	4. Examples: Ethene ( C2H4), Propene (C3H6) etc.	4. Examples: Methyl (CH3), Ethyl (C2H5) are some examples.	4. Examples: Ethyne (C2H2) and Propyne (C3H4), etc.
