Read the passage carefully and answer the Questions
Amines are classified as primary \(\left(1^{\circ}\right)\), secondary \(\left(2^{\circ}\right)\) and tertiary \(\left(3^{\circ}\right)\) depending upon the number of hydrogen atoms replaced by alkyl or aryl groups in ammonia molecules. Aliphatic amines are a stronger bases due to \(+I\) effect of an alkyl groups.
Intermolecular hydrogen bonding in primary and secondary amines affects the boiling points of amines. The intermolecular association is more in primary amines than in secondary amines as there are more number of hydrogen atoms available for hydrogen bond formation. Nitro compounds are reduced to amines by passing hydrogen gas in the presence of finely divided nickel, palladium or platinum and also by reduction with metals in an acidic medium. Gabriel synthesis is used for the preparation of primary amines. Primary amines react with nitrous acid to give unstable diazonium-salts which can be used to synthesize a variety of compounds.
Identify the amine possessing least basic strength

Haloalkanes can be represented by the formula

Match List-I with List-II

List-I (AC Circuit)	List-II (Phase Angle)
(A) Phase Difference between current and voltage in a pure inductive ac circuit	(I) zero
(B) Phase Difference between current and voltage in a pure resistive ac circuit	(II) \( \pi/2 \), current lags voltage
(C) Phase Difference between current and voltage in a pure capacitive ac circuit	(III) \( \tan^{-1}(\frac{X_L - X_C}{R}) \)
(D) Phase Difference between current and voltage in a series LCR circuit	(IV) \( \pi/2 \), current leads voltage

Paleontological evidence for evolution refers to.

The equation of the curve whose slope is given by \(\frac{d y}{d x}=\frac{4 x}{y}, x>0, y>0\) and which passes through the point \((2,2)\) is:

A galvanometer of resistance G is converted into a voltmeter to measure upto V volts by connecting a resistance \( R_1 \) in series with the coil. If a resistance \( R_2 \) is connected in series with it, then it can measure the \( \frac{V}{3} \) volts. Find the resistance \( R_3 \) in terms of \( R_1 \) and \( R_2 \) required to be connected to convert it into a voltmeter that can read upto 3V volts :
