Answer:yes they do represent
The two
Esters along with starting materials are shown below. The missing reagents ate shown in Blue encircled in red box. First reaction is carried out in acid which increases the reactivity of carboxylic acid (
electrophilicity odf carbonyl carbon). And second reaction is carried out in the presence of Base, which increases the
Nucleophilicity of nucleophile i.e. Alcohols.
There are 4 energy sublevels are present in the principal energy level n = 4.
<h3>What is sublevels?</h3>
Sub-level is a type of level that is lower than another level or it is a part or component of a big level. S, p, d and f are the four energy levels in which electrons are present.
So we can conclude that 4 energy sublevels are present in the principal energy level n = 4.
