<u>Hydrogen bonds </u>are weak bonds that are not strong enough to hold atoms together to form molecules but are strong enough to form bonds within and around large molecules.
- The hydrogen bond is weak bond.
- The hydrogen bond is electrostatic force of attraction between hydrogen atom and more electronegative atoms or group ( like Florine , oxygen or nitrogen) which is contently bonded.
- The hydrogen bond is occur in polar , contently bond atoms in different molecules.
- Example is H-O-H or

- The positively charged hydrogen side of one water molecule is bond with negatively charged oxygen side of another molecule.

The seasons. This is because when Earth is on an angle, different parts of the world get different amounts of heat, making temperatures different, and therefore changing the environment.

Answer:
A) HCl > HClO > HBrO > HIO
Explanation:
The strength of an acid is related to the acid dissociation constant (Ka). This is the equilibrium constant for an acid. The higher the Ka, the stronger the acid.
An easier way to compare the strength of acids is through their pKa, where
pKa = -log Ka
The lower the pKa, the stronger the acid.
Let's consider the following acids and their pKa values:
HCl -7
HClO 7.54
HBrO 8.62
HIO 10.64
The order of decreasing acid strength is:
A) HCl > HClO > HBrO > HIO
