dentify the compound that does NOT have hydrogen bonding. Identify the compound that does NOT have hydrogen bonding. HF (CH3)2N(CH2) 4 CH3 H2O CH3(CH2) 4 OH CH3(CH2) 2 NH2

(CH3)2N(CH2)

Explanation:

A hydrogen bond occurs in a molecule when hydrogen is covalently bonded to a highly electronegative atom.

That means that if we are looking for a compound in which there is no hydrogen bonding, we are actually looking for the compound in which hydrogen is not directly linked to an electronegative atom.

If we look at the options carefully, the compound that has such characteristic is only (CH3)2N(CH2) which is a tertiary amine. The nitrogen is directly linked to three alkyl groups and no hydrogen atom hence the molecule does not exhibit hydrogen bonding.

1. a)c-14 has two more protons

2. d)they have different numbers of protons, neutrons, and valence electrons; they are all gases at room temperature.

3. c) iron and nickel.
