Question

$I$. Hydrogen bonds can occur in molecules when hydrogen atoms are bonded to nitrogen, oxygen, fluorine, chlorine or bromine.
$II$. Electronegativity values for elements found in the upper right corner of the periodic table are higher than values for elements located in other regions of the table.

• A. Statement $I$ is true, Statement $II$ is true
• B. Statement $I$ is true, Statement $II$ is false
• C. Statement $I$ is false, Statement $II$ is true
• D. Statement $I$ is false, Statement $II$ is false

Answer 1

The correct option is A Statement $I$ is true, Statement $II$ is true

Hydrogen bonds can occur in molecules when hydrogen atoms are bonded to nitrogen, oxygen, fluorine.Because their size is small and comparitively higher electronegative.

In periodic table, across periods electronegativity left to right increases and across group elecronegativity increases lower to upper side.
