Arrange the following elements in increasing order of electronegativity: N, O, F, C, Si Choose the correct answer from the options given below:
1 Si \({\mathrm{ < }}\) C \({\mathrm{ < }}\) N \({\mathrm{ < }}\) O \({\mathrm{ < }}\) F
2 Si \({\mathrm{ < }}\) C \({\mathrm{ < }}\) O \({\mathrm{ < }}\) N \({\mathrm{ < }}\) F
3 O \({\mathrm{ < }}\) F \({\mathrm{ < }}\) N \({\mathrm{ < }}\) C \({\mathrm{ < }}\) Si
4 F \({\mathrm{ < }}\) O \({\mathrm{ < }}\) N \({\mathrm{ < }}\) C \({\mathrm{ < }}\) Si
Explanation:
Electronegativity decreases on moving down the group and increases across the period on moving from left to right. So, the correct order is \({\mathrm{\mathrm{Si} < \mathrm{C} < \mathrm{N} < \mathrm{O} < \mathrm{F}}}\).

Assertion : Fluorine acts as a stronger oxidising agent than oxygen. Reason : Fluorine is more electronegative than oxygen.
1 If both Assertion & Reason are true and the reason is the correct explanation of the assertion.
2 If both Assertion & Reason are true but the reason is not the correct explanation of the assertion.
3 If Assertion is true but Reason is false.
4 If Assertion is false but Reason is true.
Explanation:
Both Assertion & Reason are true but reason is the correct explanation of the assertion. So the option (1) is correct.

Which bond is expected to be the least polar?
1 \(\mathrm{O}-\mathrm{F}\)
2 \(\mathrm{P}-\mathrm{F}\)
3 \(\mathrm{Si}-\mathrm{N}\)
4 \(\mathrm{B}-\mathrm{Cl}\)
Explanation:
Polarity \(\propto \triangle \mathrm{EN}\). Since \(\Delta \mathrm{EN}\) is very low for \(\mathrm{O}-\mathrm{F}\) bond polarity will be very less.
