Weekly Quiz Competition

Question 1
1 / -0

Systematic name of $$ H_{2}O $$ (oxide of hydrogen) is

A
Water

B
Hydrogen oxide

C
Oxidane

D
None of these

Solution

Systematic name of water is oxidane.
Question 2
1 / -0

Lead pipes are not suitable for drinking water because

A
A layer of lead dioxide is deposited over pipes

B
Lead reacts with air to form litharge

C
Lead reacts will water containing air to form $$Pb(OH)_{2}$$

D
Lead forms basic lead carbonate

Solution

Lead pipes are not suitable for drinking water because Lead reacts will water containing air to form $$Pb(OH)_{2}$$ which is poisonous for our health.
Hence, Option "C" is the correct answer.
Question 3
1 / -0

Hydrogen molecule differs from chlorine molecule in which of the following respect?

A
Hydrogen molecule is non-polar but chlorine molecule is polar

B
Hydrogen molecule is polar while chlorine molecule is non-polar

C
Hydrogen molecule can from intermoelcular hydrogen bonds but chlorine molecule can not

D
Hydrogen molecule cannot participate in coordination bond formation but chlorine molecule can

Solution

Chlorine has a lone pair of electrons and vacant d-orbitals, thus they can take part in coordinate covalent bond. Hydrogen molecule does not have a lone pair of electrons. So it will not take part in the coordinate bond
Both chlorine and hydrogen gas are non-polar molecules as they are bonded to the same element and have same electronegativity.
Question 4
1 / -0

The structure of $$ H_{2}O_{2} $$ is

A
planar

B
linear

C
spherical

D
non-planar

Solution

Structure of $$H_2O_2$$ is non planar as shown.
Question 5
1 / -0

The boiling point of water is exceptionally high because

A
There is covalent bond between H and O

B
Water molecule is linear

C
Water molecules associate due to hydrogen bonding

D
Water molecule is not linear

Solution

The boiling point of water is exceptionally high because water molecule associate due to inter molecular hydrogen bonding.
Question 6
1 / -0

Ionic hydrides are usually

A
Good electrically conductors when solid

B
Easily reduced

C
Good reducing agents

D
Liquid at room temperature

Solution

Ionic hydrides are good reducing agents because of the unstable $$H^-$$ ion.
Question 7
1 / -0

The oxide that gives hydrogen peroxide $$\left ( H_{2}O_{2} \right ) $$ on the treatment with a dilute acid $$ H_{2}SO_{4} $$

A
$$ MnO_{2} $$

B
$$ PbO_{2} $$

C
$$ Na_{2}O_{2} $$

D
$$ TiO_{2} $$

Solution

The oxide that gives hydrogen peroxide $$\left ( H_{2}O_{2} \right ) $$ on the treatment with a dilute acid $$ H_{2}SO_{4} $$ is $$ Na_{2}O_{2} .$$

$$ Na_2O_{2}+H_{2}SO_{4}\rightarrow Na_{2}SO_{4}+H_{2}O_{2} $$
Question 8
1 / -0

The property of hydrogen which distinguishes it from alkali metals is

A
Its electropositive character

B
Its affinity for non metal

C
Its reducing character

D
Its non-metallic character

Solution

Hydrogen is a non − metal while all other members of group 1 (alkali metals) are metals.
Question 9
1 / -0

Hydrogen can behave as a metal

A
At very high temperature

B
At very low temperature

C
At very high pressure

D
At very low pressure

Solution

Metallic hydrogen is a phase of hydrogen when it behaves as electrical conductor. At the high pressure of gigapascals hydrogen exist as a liquid metal. Liquid metallic hydrogen is thought to be present in large amount in gravitationally compressed interiors of Jupiter and Saturn.
Question 10
1 / -0

Hydrogen has a tendency to gain one electron to acquire helium configuration. In this respect it resembles

A
Halogens

B
Actinides

C
Transition elements

D
Alkali metals

Solution

Hydrogen has a tendency to gain one electron to acquire helium configuration. In this respect, it resembles Halogens.
Hence, Option "A" is the correct answer.
