Question

→ Give a test that can be used to confirm the presence of carbon in a compound.
→ With a valency of 4, how is carbon able to attain noble gas configuration in its compounds?​

Answer 1

Answer:

Burn compound in air/ oxygen; Gas (CO2) evolved turns lime water milky. Carbon has four electrons in its valence shell orbital. So, it can neither accept nor gain four electrons.

Explanation:

With valency 4 carbon is able to attain noble gas configuration by sharing its four valence electrons with other elements
