Answer 1

Answer:

Explanation:

Answer 1

Alkane:

• It is a hydrocarbon in which the atoms are connected to each other through a single covalent bond.
• The general formula of alkanes is: CnH2n+2
• They burn in air with blue and non-sooty flame.
• Alkanes undergoes substitution reactions. More over Alkanes are not able to decolorize the red-brown color of Bromine (Br2) water.

Alkene:

• It is a hydrocarbon in which the atoms are connected to each other through a double bond.
• The general formula of alkenes is: CH2n.
• They burn in air with a yellow and sooty flame.
• They undergo addition reactions and not substitution reactions and can decolorize the Red-Brown color of Br2 water.
