Explanation

The correct ascending order of reactivity of alkyl halides is F, Cl, Br, I, with fluorine being the least reactive and iodine being the most reactive.

Reactivity increases down the group as bond strength decreases.

Explanation

In Friedel-Crafts acylation, an acyl group is introduced into the benzene ring in the presence of AlCl₃ (aluminum chloride).

It acts as a catalyst by facilitating the formation of the acylium ion that reacts with the benzene.

Explanation

Most molecular crystals melt below 200°C.

Molecular crystals are composed of discrete molecules held together by weak intermolecular forces,

Such as van der Waals forces, dipole-dipole interactions, and hydrogen bonds.

Because these forces are weak, they require relatively little energy to overcome, resulting in low melting and boiling points.

Therefore, their melting points are typically well below 300°C, and often below 200°C, unlike ionic or metallic crystals, which have much stronger bonds and higher melting points

Explanation

The first product from the oxidation of a primary alcohol is an aldehyde.

1. Initial oxidation:

The primary alcohol is oxidized by the removal of two hydrogen atoms, resulting in the formation of an aldehyde functional group (-CHO). 

2. Further oxidation:

The resulting aldehyde can then be further oxidized to a carboxylic acid functional group (-COOH) by the addition of a second oxygen atom. 

Explanation

Explanation

Hydrocarbons do not have a tendency to form hydrogen bonding.

Because they lack highly electronegative atoms like oxygen or nitrogen that are necessary for hydrogen bonds.

In contrast, carboxylic acids, ammonia, and ethyl alcohol can all engage in hydrogen bonding due to their functional groups.

Explanation

To boil water at 110°C, the external pressure must be higher than normal atmospheric pressure (760 torr), typically in the range of 760 - 1200 torr. 

This increased pressure raises the boiling point of water above its standard boiling point of 100°C.

Explanation

The correct ideal gas equation is PV = nRT.

Where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin.

This equation relates these properties for an ideal gas under various conditions.

Explanation

Intermolecular forces between molecules of an ideal gas are considered absent.

As ideal gases are defined by the assumption that their particles do not attract or repel each other.

This allows them to occupy space independently and move freely.

Explanation

The correct electronic configuration for carbon is 1s²2s²2p².

Indicating it has 6 electrons: 2 in the 1s orbital, 2 in the 2s orbital, and 2 in the 2p orbital.
