Answer:

Check explanation.(Last paragraph).

Explanation:

Hydrogen bond was used to account for the Behavior of some organic compounds containing Electronegative elements such as nitrogen and oxygen. It was proposed that, '' when a Hydrogen atom lies between two highly Electronegative atoms, it shows a unique property of forming a bond between them by holding one of the atoms by a covalent bond and the other by purely electrostatic force''. This electrostatic force is known as the hydrogen bonding.

===> So, let us now answer the question properly; C- H group would be more likely to be a hydrogen bond donor group when the C is next to N because their would be separation of charge in the adjacent C-H bond which is caused by the positively charged Nitrogen (N). This will cause a C^- and a H^+, that is partial negative and positive charges on carbon and Hydrogen respectively. With this, the ease at which hydrogen will donate will increase.
