Answer:

C) HF, because it has the strongest intermolecular force

Explanation:

The electronegativity difference ΔEN between H and F is so high that HF has especially high dipole-dipole forces, which we call hydrogen bonds. They are the strongest intermolecular forces, and they are responsible for the high boiling point of HF.

A) is wrong. HI has a higher mass and more electrons than HBr.

B) is wrong. There is no hydrogen bonding in HCl.

D) is wrong. There are no ion-dipole forces in HI.

The compound 1-butene is modeled here. What would need to happen for molecules of this compound to transform into polybutene? A.

kompoz [17]

In order to form polymers, we need to chain molecules together. This involves making bonds between them.

Shifting H’s around doesn’t accomplish anything.

Forming more double bonds will have the opposite result, as it would make the molecules more stable and less likely to react with each other.

Adding oxygen to the molecule no longer makes it polybutene. That would likely result in the formation of some sort of ether, as hey would react to form a C-O-C Bond.

The only answer left is A. In order to form polyalkenes, we have to break a double bond so that it’s available to form more covalent bonds.

Hope this helps

Is insulating ability a chemical property or physical?

Maurinko [17]

The insulating ability of a substance is a physical characteristic and not a chemical one. A physical property is a characteristic that distinguishes one type of matter from the other and can be observed without changing the identity of the substance. A chemical property describes how one substance changes into another in a chemical reaction.
