2-chloropropane is treated with naoh. of the following, the most likely product to form would be a(n):
a. primary alcohol.
b. secondary alcohol.
c. aldehyde.
d. ketone.

secondary alcohol

Explanation:

NaOH in solution provides OH- nucleophile.

When 2-chloropropane is treated with NaOH, nucleophillic substitution reaction takes place.Here leaving group is Chlorine atom (Cl).

Here OH- replaces Chlorine (Cl) to form 2-propanol which is a secondary alcohol.(OH group attached to 2° carbon)

Other possibility is elimination reaction in which NaOH acts as base.

NaOH acts as base when it is concentrated and aqueous NaOH acts as nucleophile.

In that case,the product formed will be an alkene.(not there in option)

answer: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
