In a group of the periodic table, how does the size of atom A affect H-A bond strength and acid strength?

Options

  1. ALarger size of A leads to stronger H-A bond and stronger acid.
  2. BLarger size of A leads to weaker H-A bond and stronger acid.
  3. CLarger size of A has no effect on H-A bond strength and acid strength.
  4. DLarger size of A leads to stronger H-A bond and weaker acid.

Correct answer

B. Larger size of A leads to weaker H-A bond and stronger acid.

Step-by-step solution

In a group of the periodic table, as the size of atom A increases down the group, the H-A bond strength decreases, leading to stronger acids.
