The delocalized cloud of π electrons in benzene is formed by the overlap of 6 ________ orbitals.
1 answer:
The delocalized cloud of π electrons in benzene is formed by the overlap of 6<u> p-orbitals</u>.
So, option B is correct one.
In the case of hydrocarbons, delocalisation occurs in benzene rings , where a hexagon of six carbon atoms has decalized electrons spread over the whole ring.
All of the carbon atoms in the benzene rings are orbitals around the ring produces a framework of six sigma bonds, while the unhybridized p-orbitals which are perpendicular to this plane over in side-to-side fashion to form three pi-bonds.

Answer: (a) There are 0.428 moles present in 12 g of molecule.
(b) There are 2 moles present in particles of oxygen.
Explanation:
(a). The mass of nitrogen molecule is given as 12 g.
As the molar mass of is 28 g/mol so its number of moles are calculated as follows.
So, there are 0.428 moles present in 12 g of molecule.
(b). According to the mole concept, 1 mole of every substance contains atoms.
Therefore, moles present in particles are calculated as follows.
So, there are 2 moles present in particles of oxygen.
