Why is salt an ionic bond? Why is salt an ionic bond?
yaroslaw [1]
: If you mean table salt i.e. sodium chloride. It is held together by ionic bonds between sodium (Na+) and chloride (Cl-) ions. The sodium ions have a positive charge and the chlorine ions have a negative charge. Since opposite charges attract, they form ionic bonds. Ionic bonds are nothing more than the attraction between positive and negative ions.

Which of the following are strongly hydrogen bonded in the liquid phase? A) nitrilesB) esters C) secondary amides D) acid chlori
-Dominant- [34]

Answer: Option (C) is the correct answer.

Explanation:

Chemical formula of a secondary amide is R'-CONH-R, where R and R' can be same of different alkyl or aryl groups. Here, the hydrogen atom of amide is attached to more electronegative oxygen atom of the C=O group.

Therefore, the hydrogen atom will be more strongly held by the electronegative oxygen atom. As a result, there will be  strongly hydrogen bonded in the liquid phase of secondary amide.

Whereas chemical formula of nitriles is RCN, ester is RCOOR' and acid chlorides are RCOCl. As no hydrogen bonding occurs in any of these compounds because hydrogen atom is not being attached to an electronegative atom.

Thus, we can conclude that secondary amides are strongly hydrogen bonded in the liquid phase.
