Chemistry
1 answer:
LenKa [72]3 years ago

Answer:

The correct answer is: Only Reaction 1.

Explanation:

Ok, let us define what entropy is: entropy is a measure of the random activity in a system, and there are several factors which can affect the amount of entropy in a system - for example when you increase temperature, you increase entropy.

In this case,

Reaction 1: NaCl(s)  → Na+(aq)+Cl- (aq): In this reaction you are solvating the atoms of Na+ and Cl-, or in other words, you are passing a compound from the solid state to the liquid state, which causes the entropy to increase. Liquids have more energy and entropy than solids.

Reaction 2: N2(g) + 3H2(g)  → 2NH3(g): In this case you are getting a gaseous product from gaseous reactants, and although there is positive entropy, it does not increase.

telo118 [61]
The scheme is shown below, the steps involved are as follow,

Step one: Reduction:
               The carbonyl group of given compound on reduction using Wolf Kishner reagent converts the carbonyl group into -CH₂- group.

Step two: Epoxidation:
              The double bond present in starting compound when treated with m-CPBA (<span>meta-Chloroperoxybenzoic acid) gives corrsponding epoxide.

Step three: Reduction:
                The epoxide is reduced to alcohol on treatment with Lithium Aluminium Hydride (LiAlH</span>₄)<span> followed by hydrolysis.

Step four: Oxidation:
               The hydroxyl group (alcohol) is oxidized to carbonyl (ketonic group) using oxidizing agent Chromic acid (H</span>₂CrO₄).
