The correct answer is C-C bond has the longest covalent bond distance.
However, the corresponding CC bonds are weaker than the CN double and triple bonds. The strength of the C-N single bond is not always affected by its ionic or polar nature. Polar bonds like the F-H or O-H bonds, for instance, are among the strongest single bonds. The distance between the nuclei of the two atoms connected by a bond is known as the bond length. we may say that the total of the covalent radii of two bound atoms is nearly equivalent to the bond length. The angstrom unit serves as the standard unit of measurement for bond length. Several methods, including rotational spectroscopy, X-ray diffraction, and neutron diffraction, can be used to measure the bond length.

Answer:
1) correct
2) incorrect
3) correct
4)incorrect
Explanation:
1) A Lewis acid is a substance that accepts a nonbonding pair of electrons.
A Bronsted-Lowry acid is a substance that donates a proton H⁺
Since the donation of a proton involves the acceptance of a pair of electrons, every Bronsted-Lowry acid is also a Lewis acid.
2)A Lewis acid not necessarily needs to have a proton to be donated.
3) Conjugated acids of weak bases are strong acids and conjugated acids of strong bases are weak acids.
4)K⁺ comes from a strong base, therefore is does not have an acidic behaviour.
