The Correct Option is D
Solution and Explanation
PLAN $NaHCO^3 \rightleftharpoons Na^+ + HCO^{-}_{3}$
$HCO^{-}_{3}$ is decomposed by acid releasing $CO_2$
$HCO^{-}_{3} + H^+ \longrightarrow H_2O + CO_2$
If acid is stronger than $HCO^{-}_{3} $then $CO_2$ is released. Phenol is less
acidic and thus does not liberate $CO_2$ with $ NaHCO_3.$
$HCO^{-}_{3}$ is decomposed by acid releasing $CO_2$

- A single slit diffraction experiment is performed to determine the slit width using the equation, $ \dfrac{b d}{D} = m \lambda $, where $ b $ is the slit width, $ D $ the shortest distance between the slit and the screen, $ d $ the distance between the $ m^{\text{th}} $ diffraction maximum and the central maximum, and $ \lambda $ is the wavelength. $ D $ and $ d $ are measured with scales of least count of 1 cm and 1 mm, respectively. The values of $ \lambda $ and $ m $ are known precisely to be $ 600 \, \text{nm} $ and 3, respectively. The absolute error (in $ \mu\text{m} $) in the value of $ b $ estimated using the diffraction maximum that occurs for $ m = 3 $ with $ d = 5 \, \text{mm} $ and $ D = 1 \, \text{m} $ is ___.

Alcohols
What is Alcohol?
Alcohol is a derivative of water (H2O) that has one, two, or more hydroxyl groups that are attached to a carbon atom of a hydrocarbon chain (an alkyl group). It is one of the most common organic compounds used in sweeteners, fragrances, and medicine.

Uses of Alcohol:
- Ethanol is the alcohol used in alcoholic drinks. It can be used as an industrial methylated spirit where methanol is used very little in quantity as it can be dangerous.
- It is used as fuel to produce carbon dioxide and water by the process of fermentation. Whereas methanol burns carbon dioxide and water to facilitate combustion.
- Alcohol is an organic compound used as a solvent that is insoluble in water.
- It can be used to lower the level of sugar.
- Alcohol is used as a preservative in laboratories.
