Answer:
The OH group
Explanation:
Benzhydrol contains OH hydroxyl group in its molecule while fluorene does not. At first glance, one would think that OH, which contributes to hydrogen bonding would causes melting point of benzhydrol to be higher than fluorene. <em>However, </em>the structure of benzhydrol, which is 2 benzene rings connected to center hydroxyl carbon (PhCOHPh), allows for each benzene rings in benzhydrol to rotate until both rings are perpendicular to minimize repulsive force. This prevents the molecule from stacking on each other due to its non flat shape, and thus, lowering its melting point in contrast to flat fluorene molecule.
Correct Answer: option 4: <span>E and D show that the energy of the products is less than that of the reactants.
Reason:
For the reaction: Q + R </span>→ N + M
<span> (reactant) (product)
From the graph, it is clearly evitable that E represent energy of reactant, while D represents energy of products. Also, value of D is less as compared to E. This signifies that, products (N+M) has less energy as compared to reactants (Q+R). Also, the reaction is exothermic in nature.

Thermal energy because you need to boil the water and thermal energy is needed to create the heat.....
Answer:
Peptide Bonds
Explanation:
Peptide bonds are formed by a biochemical reaction that extracts a water molecule as it joins the amino group of one amino acid to the carboxyl group of a neighboring amino acid.
