True or false...if false..change the words in the parantheses to make the sentence true...?

Question

1. (Esters) are capable of forming hydrogen bonds.

2. Esters have (lower) boiling points than alcohols.

Answer 1

1. false - Carboxyllic acids or alcohols

2. lower - true

Answer 2

I should get reason to Mr. KENTUCKY.
My congrutalions to Mr. KENTUCKY.

a) Remeber, a pure compound origins "hydrogen bonds" if and only if its molecule containts "protic hydrogen" atoms.
Generally, esters are organic compounds which have not "protic hydrogen" atoms. Finally, "protic hydrogen" atoms are hydrogen atoms who bound with very electronegative atoms, like O, N, etc. (see Pauling's electronegativity).
FALSE.

b) Boiling points are correlated to secondary chemical bonds, so-called intermolecular bonds. In the overwritten, you read that esters origins not "hydrogen bonds" (generally true)...on the other hand, alcohols do it.
TRUE.

I hope this helps.

Answer 3

1. True. Esters participate in hydrogen bonds as hydrogen-bond acceptors, but cannot act as hydrogen-bond donors, unlike their parent alcohols. This ability to participate in hydrogen bonding makes them more water-soluble than their parent hydrocarbons

2.False. Alcohols are flammable so they have lower boiling point.

Answer 4

false
