3 benzene rings

After taking into account account the above observed facts, Kekule (1865) suggested a ring structure for benzene. According to him, six carbon atoms occupied six corners of a regular hexagon in benzene and each carbon carried one hydrogen atom. To satisfy the tetraval..

Halogenation of arenes is an electrophilic substitution reaction. The function of the halogen carrier is to generate 'electrophile' which attacks the benzene ring to form the product. With excess halogen, the second halogen also gets introduced in the ring at ortho and..

Physical Properties of Benzene * Benzene is a colorless liquid (melting point 5.5 o C, boiling point 80.4 o C) with a characteristic smell of petrol. * It is immiscible with water, but dissolves in organic solvents. * It is lighter than water: density 0.87..

. Hence sideways overlapping of '2p' orbitals of carbon atoms can form two sets of p -bonds as show..

Benzene is a colorless liquid (melting point 5.5C, boiling point 80.4C) with a characteristic smell of petrol. It is immiscible with water, but dissolves in organic solvents. It is lighter than water: density 0.87 g cm - 3 Its vapors are toxic..

The numbering of carbon atoms in the ring (or nucleus) is done as follows. When there is only one substituent on the ring, there is only one compound possible. Thus, numbering of the carbon atoms of the nucleus does not arises. If there are two or more substituents, then num..

The halogen atom is ortho and para directing and therefore, substitution takes place at ortho and para positions giving electrophilic substitution reactions at the benzene ring. In the resonance structures of chlorobenzene the ortho and para positions get negatively charged, i...

A bag contains 1 gold ring, 1 silver ring, and 1 diamond ring. 2 rings are drawn from the bag, one after the other without replacing the first ring drawn. Use the tree diagram to find the number of possible outcomes for the experiment. => 6 or ..

A steel wire in the form of a circular ring of radius 3 m is straightened and cut into 4 equal pieces. Find the length of each piece. => 18.84 m or 4.71 m or 3 m or 14.71 m..

A steel wire in the form of a circular ring of radius 4 m is straightened and cut into 3 equal pieces. Find the length of each piece. => 18.37 m or 8.37 m or 4 m or 25.13 m..
