Given below are two statements:
Statement - I: Along the period, the chemical reactivity of the element gradually increases from group 1 to group 18.
Statement - II: The nature of oxides formed by group 1 element is basic while that of group 17 elements is acidic.
In the light of the above statements, choose the most appropriate from the options given below:

Given below are two statements:
Statement-I: Since fluorine is more electronegative than nitrogen, the net dipole moment of $$NF_3$$ is greater than $$NH_3$$.
Statement-II: In $$NH_3$$, the orbital dipole due to lone pair and the dipole moment of NH bonds are in opposite direction, but in $$NF_3$$ the orbital dipole due to lone pair and dipole moments of N-F bonds are in same direction.
In the light of the above statements, choose the most appropriate from the options given below.

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R.
Assertion A: $$H_2Te$$ is more acidic than $$H_2S$$.
Reason R: Bond dissociation enthalpy of $$H_2Te$$ is lower than $$H_2S$$.
In the light of the above statements, choose the most appropriate from the options given below.
