Yuliya22 [10]

Answer:

Explanation:

There are many compounds that are produced from Nickel.

Molar mass of Ni = 58.7g

So for 0.235g Ni, there are 0.004M.

By conservation of mass, the compound produced will contain 0.04M of Ni.

Sulfonation of naphthalene, C10H8, results in two products. One product is kinetically favored and predominates in the beginning

Marrrta [24]

Explanation:

The sulfonation of the naphthalene yield 2 products under different conditions:

When the reaction is carried at 80 °C, 1-naphthalenesulfonic acid is the major product because it is kinetically favoured product as arenium ion formed in the transition state corresponding to 1-naphthalenesulfonic acid is more stable due to better resonance stabilization.

When the reaction is carried at 160 °C, 2-naphthalenesulfonic acid is the major product as it is more stable than 1-naphthalenesulfonic acid because of steric interaction of the sulfonic acid group in 1-position and the hydrogen in 8-position.

The products are shown in image below.
