Question

Differentiate between the following:

Alkanes and alkynes

Answer 1

Feature	Alkanes	Alkynes
Bond Type	Alkanes contain only single covalent bonds between carbon atoms.	Alkynes contain at least one triple covalent bond between carbon atoms.
Saturation	They are classified as saturated hydrocarbons.	They are classified as unsaturated hydrocarbons.
General Formula	The general molecular formula for alkanes is CnH2n+2.	The general molecular formula for alkynes is CnH2n−2.
Chemical Reactions	Alkanes primarily undergo substitution reactions under specific conditions.	Alkynes readily undergo addition reactions across their triple bond.
Bromine Water Test	Alkanes do not change the reddish-brown colour of bromine water.	Alkynes instantly decolorize the reddish-brown colour of bromine water.
