Indicate which reaction will occur faster. Explain your reasoning. Select the single best answer. Hexyl chloride or cyclohexyl chloride with sodium azide in aqueous ethanol

The question is incomplete, the complete question is;

Indicate which reaction will occur faster. Explain your reasoning. Select the single best answer Hexyl chloride or cyclohexyl chloride with sodium azide in aqueous ethanol O Cyclohexyl chloride reacts faster because it is more soluble in the solvent OHexyl chloride reacts faster because it is less sterically hindered. O Cyclohexyl chloride reacts faster because its carbocation intermediate is more stable. Hexyl chloride reacts faster because hydrogen abstraction is more likely to occur in this compound.

Hexyl chloride reacts faster because it is less sterically hindered.

Explanation:

Now we have to think through the problem carefully. We must remember that the azide ion is a good nucleophile. Being a good nucleophile, we should be thinking about an SN2 reaction mechanism.

Though ethanol is a polar protic solvent which may weaken the nucleophile by hydrogen bonding, the nucleophile will still react very fast with a primary alkyl halide such as hexyl chloride via SN2 mechanism.

The substrate is easily accessible to the azide ion in hexyl chloride compared to cyclohexyl chloride hence hexyl chloride reacts faster than cyclohexyl chloride.

the best answer is d because the strong cohesion is caused by the ability of water molecules to undergo hydrogen bonding.

a is incorrect because when water solidifies, it becomes   ice, which expands and occupies a bigger volume for the same mass of water in its liquid state.

b is incorrect because water has high surface tension. besides bonding to itself it hydrogen bonds to other molecules at the top decreasing possibility for breaking of attractive forces.

c is incorrect because the water molecule has oxygen which is highly electronegative and so pulls the electron pair towards itself creating a dipole moment, making the molecule polar.

e is incorrect because water has strong adhesion, ability to stick to other molecules such as glass because of this molecules having stronger hydrogen bonding than water.
