Correct statements from the following are: A. Nitrogen in oxidation...
Correct statements from the following are:
A. Nitrogen in oxidation states from to disproportionates in acid medium.
B. Nitrogen has the ability to form multiple bonds with itself and other elements with small size and high electronegativity.
C. N-N single bond is stronger than P-P single bond.
D. Nitrogen has highest density in its group due to small size.
E. The maximum covalency of nitrogen is four since it has only four valence orbitals for bonding.
Choose the correct answer from the options given below:
A. Nitrogen in oxidation states from to disproportionates in acid medium.
B. Nitrogen has the ability to form multiple bonds with itself and other elements with small size and high electronegativity.
C. N-N single bond is stronger than P-P single bond.
D. Nitrogen has highest density in its group due to small size.
E. The maximum covalency of nitrogen is four since it has only four valence orbitals for bonding.
Choose the correct answer from the options given below:
Options
- AB, C and D Only
- BC, D and E Only
- CA, C and E Only
- DA and E Only
Correct answer
D. A and E Only
Step-by-step solution
Statement A is correct. Nitrogen in oxidation states from to tends to disproportionate in acidic medium. For example, .
Statement B is incorrect. Nitrogen does not have d-orbitals in its valence shell, so it cannot form multiple bonds. It forms multiple bonds.
Statement C is incorrect. The N-N single bond is weaker than the P-P single bond due to high interelectronic repulsion between the non-bonding electrons, which arises from the small N-N bond length.
Statement D is incorrect. Density increases down the group in group 15. Nitrogen is a gas and has the lowest density in its group, while bismuth has the highest.
Statement E is correct. Nitrogen has only four valence orbitals (one 2s and three 2p orbitals) available for bonding. Therefore, its maximum covalency is restricted to four.
Thus, only statements A and E are correct.
Answer: A and E Only
Statement B is incorrect. Nitrogen does not have d-orbitals in its valence shell, so it cannot form multiple bonds. It forms multiple bonds.
Statement C is incorrect. The N-N single bond is weaker than the P-P single bond due to high interelectronic repulsion between the non-bonding electrons, which arises from the small N-N bond length.
Statement D is incorrect. Density increases down the group in group 15. Nitrogen is a gas and has the lowest density in its group, while bismuth has the highest.
Statement E is correct. Nitrogen has only four valence orbitals (one 2s and three 2p orbitals) available for bonding. Therefore, its maximum covalency is restricted to four.
Thus, only statements A and E are correct.
Answer: A and E Only
