NEET Important Questions of P Block Elements with Answer Key - Free PDF

NEET (UG), which stands for the National Eligibility cum Entrance Test (Undergraduate), formerly known as the All India Pre-Medical Test (AIPMT) is an entrance exam for the students who want to pursue medical science as their major field in the future. While choosing NEET, one is eligible to undertake undergraduate courses in MBBS, BDS, BMS, BSMS, etc., from Indian institutions and universities abroad as well. A total of around 66,000 seats are available for MBBS and BDS in general. Earlier the administration of NEET (UG) was under the control of the Central Board of Secondary Education from the years 2013 to 2018. Later, it was confined to the hands of the National Testing Agency (NTA) from the year 2019.

FAQs on P Block Elements NEET Questions with Solutions

1. How does the reactivity of Phosphorus differ from Nitrogen?

Nitrogen is a less reactive compound in terms of Chemistry. The triple bond between its two nitrogen atoms makes nitrogen less reactive as compared to phosphorus. Because of the small size of nitrogen, it inhibits π−π with itself, which is not the case in phosphorus as it holds only a single bond and hence is more reactive in comparison with nitrogen. One other factor which lies for the phosphorus to act differently is about its atoms, which do not pair up and bond with their neighbouring atoms because of no π−π bonds

2. What is the difference between red phosphorus and white phosphorus?

The physical difference which lies in between red and white phosphorus is about their appearance where red phosphorus is a dark red coloured compound whereas white phosphorus is a translucent sticky solid which becomes yellow as soon as it is exposed to light. White phosphorus on the other hand is highly toxic, whereas red phosphorus is a nontoxic allotrope of phosphorus. Red phosphorus catches fire above the temperature of 240°C and white phosphorus ignites around the temperature of 50°C.

3. How does fluorine form many oxoacids? Explain.

Fluorine is an electronegative element having an electronegativity of 4. It does not have d-orbitals, and because of the absence of the same, it can not form oxoacids which have oxidation states as higher as +3, +5, or +7. The only +1 oxidation state which is shown with regard to fluorine is with the oxygen with 3.5 electronegativity. And therefore, HOF, also known as Hypofluorous acid is the only one oxoacid which is formed by fluorine.

4. Why are there no ionic compounds formed from carbon?

The valency of carbon is 4. For it to make an ionic bond, carbon has to either lose 4 electrons or have to gain 4 electrons. On the other hand, it is tough for a nucleus to carry 6 protons in 10 electrons single handedly. And if it is losing electrons, it will need a lot of energy from the side of the nucleus to lose 4 electrons and hold 6 protons in just 2 electrons. Hence, carbon does not form any kind of ionic compound.

5. Why do noble gases have low boiling points?

Noble gases or inert gases are monatomic and have the configuration 1s2 2s2 3p6, hence a complete shell configuration with completely filled valence shells. They have zero interatomic forces and strong intermolecular forces, other than weak dispersion forces acting along. Also, they can not tolerate heat. Hence, they have a very low boiling as well as melting points as compared to other elements of the same group.
