Question 1
1 / -0

Which one of the following is not a physical property of water?

A
Water has low specific heat capacity

B
It expands on cooling

C
It is odorless and tasteless

D
The boiling point of water is $$100^\circ C$$

Solution

Water has high specific heat capacity. The other options are physical properties of water.
Question 2
1 / -0

Hydrogen is a non-metal having __________electron in the valence shell.

A
1

B
2

C
3

D
4

Solution

Hydrogen is a non-metal having $${ 1e }^{ - }$$ in its outer most shell (valence shell).
Question 3
1 / -0

Which one of the following property is high in the case of water?

A
Surface tension

B
Specific heat

C
Heat of vaporization and heat of fusion

D
All of the above

Solution

Physical properties of water
1.Boiling Point and Freezing Point.
2.Surface Tension, Heat of 3.Vaporization, and Vapor Pressure.
4.Viscosity and Cohesion.
5.Solid State.
6.Liquid State.
7.Gas State.
8.High specific heat capacity.
Question 4
1 / -0

Hydrogen exhibits:

A
electropositive character

B
elctronegative character

C
Both A and B

D
None of the above

Solution

Hydrogen has one electron in its outermost shell. It can lose electron as well as gain electron to complete its octet. So it can exhibit both characters.
Question 5
1 / -0

Which symbol is used for the element hydrogen?

A
$$Hg$$

B
$$He$$

C
$$H$$

D
$$Ho$$

E
$$Hf$$

Solution

Hyrogen is represented as $$H$$
Question 6
1 / -0

Sodium on reaction with cold water produces a residue. The nature of residue is:

A
colourless, slippery and slightly cold

B
colourful, soapy and slightly warm

C
colourless, soapy and slightly warm

D
colourful, slippery and slightly cold

Solution

Sodium reacts with cold water to form $$NaOH$$. It is colourless, soapy and slightly warm.
Question 7
1 / -0

Which element has neither definite shape nor volume?

A
Sodium

B
Hydrogen

C
Iodine

D
Lithium

Solution

Hydrogen is a gas, hence it has neither definite shape nor volume.
Question 8
1 / -0

Which position for hydrogen explain all its properties?

A
At the top of halogens

B
At the top of alkali metals

C
At the top of carbon family

D
None of these

Solution

Position of hydrogen is not justified in the periodic table because it has properties of more than 1 group elements.
Question 9
1 / -0

Water $$\left({H}_{2}O\right)$$ is liquid while all other molecules of equivalent and even higher molecular weight are present in gaseous state because of

A
Covalent bonding between Hydrogen and Oxygen.

B
Electrostatic attraction among water molecules.

C
Hydrogen bonds.

D
Ionic bonds.

Solution

In $$H_2O$$ there is hydrogen bonding because oxygen has a high electronegativity(only second to flourine). so, the hydrogen atoms from other molecules of water forms a hydrogen bonds with oxygen resulting in intermolecular hydrogen bonding, which results liquid form of water.
Question 10
1 / -0

In what respect is the electronic configuration of hydrogen and halogens similar?

A
Hydrogen and halogens have one electron in their outermost shell

B
Hydrogen and halogens have one electron less than noble gas configuration

C
Hydrogen and halogens can lose one electron

D
Hydrogen and halogens show noble gas configuration

Solution

Hydrogen has one electron in its only shell. Hence, it needs one more electron to attain stable duplet electronic configuration. On the other hand, halogens have seven electrons in its valence shell. They also need one more electron to attain stable octet configuration. Therefore, they are similar in a way that they have one electron less than noble gas configuration.
