brimine and chlorine are in group 7 and they both form diatomic molecule. however bromine molecule exist as liquid at room temp
Ne4ueva [31]

Answer: difference in Vander Waals forces

Explanation:

The intermolecular force of attraction between the molecules in chlorine is WEAKER than that of Bromine.

This force is known as VANDER WAALS forces. And it DECREASES down the group; so Chlorine which is placed higher is a GAS, while Bromine placed lower in Group 7 is a LIQUID.

I need help with organic chemistry!!!
nadya68 [22]

Answer:

CHO2- ion

Explanation:

We have the lewis structure of a formate-ion here

This is CHO2-.

The carbon atom is the central atom in the structure. It's the least electronegative atom (C). Carbon has 4 valence electrons. Oxygen has 6 valence electrons.

The carbon will bind with 1 hydrogen atom, this will form 1 single bond, because hydrogen has 1 valence electron.

The carbon will bind with oxygen via a double bond.

Since carbon has only 4 valence electrons, it can only form 1 bond with the other oxygen atom.

There will formed 1 double bond between C and O and 1 single bond between C and O resulting in a negative charged O-atom.

This means there are two resonance structures. for the CHO2-  ion
