Question

What is covalent bond? How many such

bonds are present in ethane? Write two

characteristic features of covalent

compounds.​

Answer 1

COVALENT BONDS:-)

The bonds which are formed by mutual sharing of electrons between two or more than two atoms is generally known as covalent bonds.

Structure of Ethane:-

$CH_3-CH_3$

There is one covalent bond(-)present in the structure of ethane.

Features of covalent compounds:-)

1》

Covalent compound exist in liquid or gaseous state, due to weak covalent bond exceptionally glucose, urea are exist in solid state but they are covalent due to strong vanderwall force.

2》

Covalent compounds have low melting and boiling point due to weak Bond.

3》

Mostly covalent compounds are partially soluble or insoluble in water .

Answer 2

$\Huge{\underline{\red{\mathsf{Answer:-}}}}$

1) What are Covalent Bonds ?

Answer :-

The bonds which are formed by "sharing of the electrons". Mostly Carbon Compounds form this type of Bonds.

2) Bonds Present in Ethane

Answer :-

$\large{\implies}{\boxed{\boxed{\red{CH_{3} \: - \: CH_{3}}}}}$

In Ethene 1 Covalent Bond is present.

3) Characeristics of Co-Valent Bond

Answer :-

(i) They have low melting and low boiling point.

(ii) Poor conductor (Insulator) of Heat and Electricity.

(iii) Formed by Non-Metals.

(iv) They are intermolecular chemical Bonds .
