Question

Use the chemical equation and the bond diagram to answer the question.

2H2 + O2 → 2H2O

2H–H + O=O → 2H–O–H

The energy of the H–H bond is 432 kJ/mol. The energy of the O=O bond is 498 kJ/mol. The energy of the O–H bond is 467 kJ/mol.

Which bond is the weakest?

(1 point)

O–O
H–H
O–H
O=O

Answer 1

O-H bonds are the weakest bond.

O-H bonds:

• Hydrogen bonding interplay including a hydrogen atom situated 'tween a pair of different atoms bearing a extreme closeness for electrons; such a bond is feebler than an concerning ancient culture bond or covalent bond but more powerful than truck der Waals forces.
• Hydrogen bonds can live between atoms indifferent particles or transportable of the alike fragment. One modicum of the pair (the backer), mainly a fluorine, nitrogen, or oxygen iota, is covalently shackled to a hydrogen crumb (―FH, ―NH, or ―OH), whose electrons it shares unequally; allure extreme energized matter closeness causes the hydrogen to oppose a slight positive charge.
• The different iota of two together, likewise usually F, N, or O, has an alone electron pair, that gives it a slight negative charge. Mainly through electrostatic allure, the contributor modicum efficiently shares its hydrogen accompanying the one who receives iota, making a bond.
• Because of allure far-reaching hydrogen bonding, water (H2O) is liquid over a far better range of hotnesses that hopeful anticipated for a fragment of its amount.

Answer 2

Answer:

Given below is the answer

Explanation:

The weakest bonds are O-H bonds.

O-H ties:

The interaction of hydrogen atoms with other atoms that have extremely near electron distances results in a link that is weaker than a covalent bond or an old culture bond but stronger than van der Waals forces.

Between atoms in separate particles or components of the same fragment, hydrogen bonds may exist. One component of the pair, known as the "backer," often an iota of fluorine, nitrogen, or oxygen, is covalently bound to a hydrogen fragment (FH, NH, or OH), with which it shares the electrons unequally, causing the hydrogen to resist a very little positive charge.

The distinct iota of two together has an isolated electron pair, which is typically F, N, or O.
