Which of the following statements is true about hybridization?

In the hydrocarbon, The state of hybridization of carbons 1,3,5 are in the following sequence:

Hybridized carbon atom used in the formation of the compound CH3— CH CH — CH2 — CH3 are:

The hybridization of carbon atoms in C—C single bond of H — C C — CH CH2 is:

Assertion: Ethylene is more reactive than ethane. Reason: Ethylene possess pi bond.

In which bond angle is the highest

Assertion: NF is a weaker ligand than N CH . Reason: NF ionizes to give Fions in aqueous solution.

Assertion : Tropylium cation is aromatic in nature. Reason :The only property that determines its aromatic behaviour is planar structure.

Assertion: A compound with delocalised electrons is more stable than that compound would be if all its electrons were localised. Reason: The extra stability, a compound gains as a result of having delocalised electro…

Assertion : The carbocation CF CH is less stable than CF . Reason : In case of CF CH ,CF is strong electron withdrawing, therefore increases +ve charge whereas in CF , lone pair of ‘F’ overlap with vacant p-orbi…

Assertion : Carbanions like ammonia have pyramidal shape. Reason : The carbon atom carrying negative charge has an octet of electrons.

In a closed room of 1000 m3, a perfume bottle is opened up. The whole room develops smell. This is due to which property of gases ?

The compressibility factor for an ideal gas is

The compressibility factor (Z) is the ratio of I. PV and nRT II. Actual molar volume of gas to molar volume of it. Choose the correct option.

Positive deviation from ideal behaviour takes place because of

The compressibility factor of an ideal gas is

For H2 gas, the compressibility factor, Z = PV/n RT is:

The compressibility of a gas is less than unity at STP. Therefore

At high pressure, all the gases have

Dominance of strong repulsive force among the molecules of the gas (Z = compressibility factor)
