Answer:
The equilibrium for hydrate formation depends both on steric and electrical factors of the carbonyl as discussed in the previous section. In most cases the resulting gem-diol is unstable relative to the reactants and cannot be isolated. Exceptions to this rule exist, one being formaldehyde where the small size of the hydrogen substituents relative to aldehydes and ketones favor hydrate formation. Thus, a solution of formaldehyde in water (formalin) is almost exclusively the hydrate, or polymers of the hydrate. The addition of electron donating alkyl groups stabilized the partial positive charge on the carbonyl carbon and decreases the amount of gem-diol product at equilibrium. Because of this ketones tend to form less than 1% of the hydrate at equilibrium.

Answer: All of the planets in our solar system orbit around the Sun. Planets that orbit around other stars are called exoplanets. environment.
Explanation:
Naphthalene balls are used to protect clothes from insects because, when they deteriorate, they create a gas that kills some insects. The naphthalene ball gradually decreases because naphthalene goes through sublimation at room temperature.
