1. Multiple choice questions.

Q1. Which of the following is the most electronegative element among Group 17 elements?

(a) Fluorine
(b) Chlorine
(c) Bromine
(d) Iodine

Answer: (a) Fluorine

Q2. The inert pair effect is most prominent in which of the following groups?

(a) Group 13
(b) Group 15
(c) Group 16
(d) Group 14

Answer: (d) Group 14

Q3. Which element of Group 13 forms a polymeric hydride?

(a) Boron
(b) Aluminium
(c) Gallium
(d) Thallium

Answer: (a) Boron

Q4. Which of the following oxides is amphoteric in nature?

(a) B$_2$O$_3$
(b) Al$_2$O$_3$
(c) Ga$_2$O$_3$
(d) Tl$_2$O$_3$

Answer: (b) Al$_2$O$_3$

2. Very Short Answer (VSA).

Q1. State the electronic configuration of nitrogen (Group 15).

Answer: The electronic configuration of nitrogen is 1s$^2$ 2s$^2$ 2p$^3$.

Q2. Why is fluorine more reactive than chlorine?

Answer: Fluorine is more reactive due to its smaller size and higher electronegativity compared to chlorine, leading to stronger oxidizing power.

Q3. Name the first element of Group 13.

Answer: The first element of Group 13 is boron (B).

3. Short Answer Questions.

Q1. Explain why boron differs in its properties from the rest of the Group 13 elements.

Answer: Boron is a non-metal, unlike the other metallic Group 13 elements, due to its small size, high ionization energy, and absence of d orbitals. It forms covalent compounds, shows limited coordination number, and does not form simple ionic compounds like aluminium or gallium.

Q2. Discuss the trend of acidic and basic character of oxides across Group 15 elements.

Answer: The acidic character of oxides decreases from nitrogen to bismuth, while basic character increases. Nitrogen and phosphorus oxides are acidic, arsenic and antimony oxides are amphoteric, and bismuth oxide is predominantly basic due to increasing metallic character down the group.

4. True or False Questions.

Q1. Oxygen is more electronegative than sulphur.

Answer: True

Q2. All group 18 elements possess a stable octet electronic configuration.

Answer: False

Q3. Down the group, the tendency to show higher oxidation state decreases for Group 15 elements.

Answer: True

3. Fill in the Blanks Questions.

Q1. __________ is the only metalloid in Group 14.

Answer: Silicon

Q2. The general electronic configuration of Group 16 elements is __________.

Answer: ns$^2$np$^4$

Q3. Xenon forms compounds mainly with __________ and oxygen.

Answer: Fluorine

How understanding P-Block Elements helps NEET Chemistry
