carbon
hydrogen
Explanation:
From the given choices, carbon and hydrogen are considered to have a relatively weak degree of electronegativity.
Electronegativity of an element is the tendency with which the atoms of the element attracts valence electrons in a chemical bond.
- Oxygen and nitrogen are highly electronegative elements having a strong attraction for electrons in covalent bonds.
- Carbon and hydrogen have considerably low electronegative values.
According to the Pauling's table showing electronegativities of elements,
N - 3.0
O - 3.5
C - 2.5
H - 2.1
therefore the order of increasing electronegativity is:
H < C < N < O
