Statement-1: All C-C bonds are equal in [10]-Annulene. and Statement-2: [10]-Annulene is a non aromatic compound

Statement-1: All C-C bonds are equal in [10]-Annulene. and Statement-2: [10]-Annulene is a non aromatic compound

Explain the meaning of 10% law.

This question has statement I and statement II . of the four choices given after the statements choose the one that best describes the two statement Statement-I (10) Annulene is not aromatic though it contains Huckel number of pi electrons. statement-II Steric interaction between internal makes in non-polar.

Which of the following is a nonaromatic.

How many of the following statements are correct? i) In cyclobutadiene two unpaired pi electrons are Present in pi nonbonding molecular orbitals which are responsible for destabilization of cyclobutadiene. ii) Cyclopentadiene pKa value is less than that of cycloheptatriene iii) Dipole moment of I^(st) Structure is more than II^(nd) Structure in the following iv) Cycloheptatrienyl bromide is less soluble in H_(2)O than in non-polar solvent v) Due to anti aromatic nature [4]-annulene is less stable than [6]-annulene

Explain the 10% law.
