NEET Questions
1. 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 $C_2H_5OH$
3. 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
4. At a certain temperature in a 5 L vessel, 2 moles of carbon monoxide and 3 moles of chlorine were allowed to reach equilibrium according to the reaction,$CO + Cl_{2} <=> COCl_2 $ At equilibrium, if one mole of CO is present then equilibrium constant $(K_c)$ for the reaction is :
- 2
- 2.5
- 3
- 4
5. 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
6. Minority carriers in a $p-type$ semiconductor are
- Holes
- Free electrons
- Both holes and free electrons
- Neither holes nor free electrons
