b) Alkynes suffer less steric hindrance during adsorption on the surface of metal catalyst.
Hence, alkynes are more reactive than alkene towards catalytic hydrogenation.
c) Oxidation of alkenes with the help of ozone can give alcohols, aldehydes, ketones, or carboxylic acids.
Alkynes undergo ozonolysis to give acid anhydrides or diketones. If water is present in the reaction, the acid anhydride undergoes hydrolysis to yield two carboxylic acids.
d) The triple bonds of alkynes, because of its high electron density, are easily attacked by electrophiles, but less reactive than alkenes due to the compact C-C electron cloud.
Hence, alkynes are more reactive than alkene towards catalytic hydrogenation.

Relative Reactivity of Alkynes and Alkenes
Alkynes and alkenes are both unsaturated hydrocarbons, but they differ in terms of their reactivity. Let's explore the correct statements regarding the relative reactivity of alkynes and alkenes.
Electrophilic Addition Reaction:
a) Alkynes are more reactive than alkenes in electrophilic addition reactions.
In electrophilic addition reactions, a π bond is broken and a new σ bond is formed. Alkynes have two π bonds, while alkenes have only one π bond. The presence of multiple π bonds in alkynes makes them more reactive towards electrophilic addition reactions compared to alkenes.
Catalytic Hydrogenation:
b) In catalytic hydrogenation, alkynes are more reactive than alkenes.
Catalytic hydrogenation is a reaction in which hydrogen gas (H2) is added across the double or triple bond of an unsaturated hydrocarbon. Alkynes are more reactive in catalytic hydrogenation because they have a triple bond, which is easier to break compared to the double bond present in alkenes. This results in the complete reduction of alkynes to alkanes, while alkenes are only partially reduced to alkanes.
Products of Addition Reactions:
c) Alkynes give acids, while alkenes give aldehydes and ketones.
When alkynes undergo addition reactions, they form carboxylic acids as the final product. This is because the triple bond in alkynes can be completely broken, allowing for the addition of multiple functional groups, such as hydroxyl groups (-OH), resulting in the formation of acids.
On the other hand, alkenes give aldehydes and ketones as the final products in addition reactions. This is due to the partial reduction of the double bond, resulting in the addition of one or two functional groups, such as carbonyl groups (C=O).
Reactivity in Halogen Addition Reactions:
d) Alkynes are less reactive than alkenes in addition reactions with halogens.
In halogen addition reactions, alkynes are less reactive compared to alkenes. This is because the triple bond in alkynes is stronger and more stable than the double bond in alkenes. As a result, breaking the triple bond requires more energy, making the addition of halogens to alkynes less favorable compared to alkenes.
In summary, alkynes are more reactive than alkenes in electrophilic addition reactions and catalytic hydrogenation. Alkynes give acids as products in addition reactions, while alkenes give aldehydes and ketones. However, alkynes are less reactive than alkenes in halogen addition reactions.
