NEET Questions
1. A coil of inductive reactance $1/ \sqrt{3}\, O$ and resistance $1 \, \Omega$ is connected to a $200\, V$, $50\,Hz \,A.C.$ supply. The time lag between maximum voltage and current is
- $\ce{\frac{1}{300} \,s}$
- $\ce{\frac{1}{600} \,s}$
- $\ce{\frac{1}{500} \,s}$
- $\ce{\frac{1}{200} \,s}$
2. A colourless, neutral, paramagnetic oxide of Nitrogen $'P'$ on oxidation gives reddish brown gas $Q$. $Q$ on cooling gives colourless gas $R$. $R$ on reaction with P gives blue solid $S$. Identify $P , Q , R , S$, respectively
- $N _{2} O\, NO\, NO _{2} \,N _{2} O _{5}$
- $N _{2} O\, NO _{2}\, N _{2} O _{4} \,N _{2} O _{3}$
- $NO \,NO _{2} \,N _{2} O _{4}\, N _{2} O _{3}$
- $NO \,NO\, N _{2} O _{4} \,N _{2} O _{5}$
3. The reagent which can do the conversion $CH _{3} COOH \longrightarrow CH _{3}- CH _{2}- OH $ is
- $LiAIH_4$ / ether
- $H_2, Pt$
- $NaBH_4$
- $Na$ and $C_2H_5OH$
4. Write a balanced equation for the reaction of molecular nitrogen (N2) and oxygen (O2) to form dinitrogen pentoxide. \((f(x)=x^2)\)
Write a balanced equation for the reaction of molecular nitrogen (N2) and oxygen (O2) to form dinitrogen pentoxide. \((f(x)=x^2)\)
- N2 + O2 → N2O5 (unbalanced equation)
- 2N2 + 5O2 → 2N2O5
- option 3
6. A parallel plate air capacitor is charged to a potential difference of V volts. After disconnecting the charging battery the distance between the plates of the capacitor is increased using an insulating handle. As a result the potential difference between the plates
- increases
- decreases
- does not change
- becomes zero
