Question

at happens as two hydrogen atoms approach each other and the distance between the two nuclei decreases? View Available Hints) 0Attractive forces increase and are greater than the repulsive forces o The forces are always eual regardless of the distance which achieves a balance O Repulsive torces Increase and are greater than the attractive forces The answer depends onthe specific molecule Subnt Feedback Which of the following covalent bonds has higher bond dissociation energy? View Available Hint(s) OH-O -F - Which of the following elements has the highest electronegativity? View Available Hint(s) o Mg

Explanation / Answer

1. The answer is A.

when the two atoms are approaches to each other inthe formation a molecule, both repulsive and attractive forces are present. But attractive foreces are dominating than the repulsive foreces. so the distance between the nucleous is decreases in the formation of molecule.

2.The answer is C.

H-F bond has more dissociation energy due ot more electronegativity of Fluorine atom.

3.The answer is C.

Cl has highest electronegativity. Cl atom belongs to 17 th group element. In a period from left to right size of the atom is decreases. then electonegativity values is increases. So Cl has highest E.N.Its values is 3.0.
