Check Answer and Solution for above.

. In B 4π electrons does not obey the 4n2π rule so anti-aromatic. Which of the following compounds is not. 1 BOH3 and H3PO3 2 BOH3 and AlOH3 asked Aug 3 2021 in Chemistry by Kanishk01 459k points jee.

D is non aromatic because of sp 3 carbon in the ring. Give reasons for each answer. Since the value of n is not an integer the given.

Anti-aromaticity is a characteristic of a cyclic molecule with a π electron system that has higher energy due to the presence of 4n delocalised π or lone pair electrons in it. For 78 dihydronaphthalein H It is cyclic planar but the electron cloud is not in. Unlike aromatic compounds which follow Hückels rule 4 n 2 π electrons and are highly stable anti.

It is cyclic not planar. Which of the following compounds is not considered to be aromatic. By Huckels rule 4n 2 8.

CH3 H CH3-CH2 H ос H CH2-CH3. Asked Jan 5 in Chemistry by ShivrajSharma 249k points class-12. It is not an aromatic compound.

B Not planar Hence it is non-aromatic. For cyclopenta-13-diene anion G It is cyclic planar and has 6π conjugated electrons that means all the pi electrons are in continuous delocalization hence we consider negative charge in conjugation. B is anti-aromatic with 4 π e.

They undergo substitution reactions more favourably than addition reaction these properties are not present in cyclohexane. In C 8π electrons does not obey the 4n2π rule so anti-aromatic. What is the decreasing order of reactivity amongst the following compounds towards aromatic electrophilic substitution I.

The correct option is 1 B C and D. Hence it is non aromatic in nature. For a compound to be aromatic the value of n must be an integer n 0 1 2.

Which of the following compounds is not aromatic. 2 0 03 O d4 Which of the following compounds is trans-3-hexene. Benzenoids are the compounds having at least one benzene ring.

C is anti-aromatic with 8 π e. A Image A B Image B C Image C D Image D. Hence is not aromatic.

Hence cycloheptatrienyl anion is not an aromatic compound. In A 2π electrons obeys the 4n2π rule cyclic and conjugated so aromatic. In the last we can conclude that phenol naphthalene and pyridine are aromatic compounds.

The set in which compounds have different nature is. Orbitals of one carbon atom are not in conjugation. Hence the correct option is option A.

Option 3Out of 8π electrons it has delocalized 6π electrons in one six-membered planar ring which do not follows Huckels rule due to which it will be. It is not aromatic. It does not obey huckles rule.

Which one of the following compounds is non-aromatic. Which of the following compounds is not aromatic. Aromatic compounds are characterised by their unusual stability delocalisation of π -electrons in a planar ring.

The correct option is B B C and D. So the correct answer is Option D. For a compound to be aromatic the value of n must be an integer n 0 1 2 which is not true for given compound.

CH-CH2 CH3 CH3-CH2 b. Aromatic compounds are categorized further into two categories ie. Option 1 Has 8π electrons does not follow Huckel rule.

Hence it is aromatic. Option 2Has 6π delocalized electrons. A Classify the following compounds as aromatic antiaromatic or nonaromatic.

Correct option is A a Number of π electrons 4. Hence compoundsions of options B and D are aromatic. The compoundsions in options B and D have 6 pi electrons.

They are cyclic planar and conjugated systems of pi electrons.
