Question

at ordinary temperature H20 is liquid but h2s is gas give reason​

Answer 1

Explanation:

This is because, H20 has intermolecular hydrogen bond between it's molecule (H-O-H------H-O-H) while H2S has weak Van Der Wals forces between it's molecule.Hence the molecules of H2O are strongly packed than H2S,thus water is at liquid state at room temperature,

Answer 2

Explanation:

ability of Oxygen atom to pull

electrons is greater than of Sulfur

ie. O is more electronegetive th an

S. When an hydrogen is connected

to an highly electronegative element

like Oxygen (this usually happens

with fluorine, oxygen, and nitrogen), it

has higher intermolecular forces like

Hydrogen bonding. Its a very strong

bond that packs the water molecules

closely together, forming a liquid while

sulfur does not attract H nearly

as strongly so they dissociate into a

gas. Thus, H20 has intermolecular

hydrogen bond between it's molecule

(H-0-H---- --H- 0 -

H) while H2S has weak van Der Waals

forces between it's molecule. Hence the

molecules of H:0 are strongly packed

than H2S ,thus water is at liquid state

at room temperature,
