Compound A and compound B are constitutional isomers with molecular formula C3H7Cl. When compound A is treated with sodium metho
mars1129 [50]

Answer:

Compound A and compound B are constitutional isomers with molecular formula C3H7Cl.

When compound A is treated with sodium methoxide, a substitution reaction predominates. When compound B is treated with sodium methoxide, an elimination reaction predominates.

Explanation:

Constitutional isomers are the one which differs in the structural formula.

When compound A is treated with sodium methoxide, a substitution reaction predominates.

That means sodium methoxide is a strong base and a strong nucleophile.

But when it reacts with primary alkyl halides it forms a substitution product and when it reacts with secondary alkyl halide it forms mostly elimination product.

The reaction and the structures of A and B are shown below:

Which of the following statements about the formation of a solution is true?
bekas [8.4K]

<span>In the formation of a solution, energy is required to overcome the forces of attraction between the solvent particles. The first step is for the solvent particles to move in order for solute particles to enter the system. This process is endothermic where energy flows into the system. The second step is when solute particles must separate from other solute particles. Lastly, the solute should move between solvent particles.</span>
