The concentration of the diluted solution is 0.0625 M.

<h3>What is concentration?</h3>

The term concentration refers to the amount of substance present in solution.

1) To find the mass of the compound;

mass/134 g/mol = 1.40x10-2M × 100/1000

mass = 1.40x10-2M × 100/1000 × 134 g/mol

mass = 0.19 g

2) To find the molarity of the solution;

2.50 g/40 = 100/1000 × M

M = 2.50 g/40 × 1000/100

M = 0.625 M

3) Using;

C1V1 = C2V2

0.625 M × 10.00mL = C2 × 100.00 mL

C2 = 0.625 M × 10.00mL/ 100.00 mL

C2 = 0.0625 M

vagabundo [1.1K]

Answer:

Four substitution products are obtained. The carbocation that forms can react with either nucleophile (H2O or CH3OH) from either the top or bottom side of the molecule

Explanation:

An SN1 reaction usually involves the formation of a carbocation in the slow rate determining step. This carbocation is now attacked by a nucleophile in a subsequent fast step to give the desired product.

However, the product is obtained as a racemic mixture because the nucleophile may attack from the top or bottom of the carbocation hence both attacks are equally probable.

The attacking nucleophile in this case may be water or CH3OH
