How many N-H Stretching bands observed in the IR spectrum of primary Amines ($R-NH_2$)?

Identify the compound which shows mass spectrum: $m/z = 60$ (100%), $m/z = 61$ (3%), $m/z = 62$ (0.2%)

Which one of the following is used as internal standard in NMR analysis?

Relative rate of alkaline hydrolysis of the following compound: 4-R-ethyl benzoate where R is: (A) $NO_2$, (B) $Cl$, (C) $H$, (D) $CH_3$, (E) $OCH_3$

Assertion (A): HBr addition to alkenes gives Markonikov addition. Reason (R): HBr addition to alkene in the presence of peroxide gives Anti-Markonikov addition as the reaction proceeds via radical mechanism.

Assertion (A): Carbon halogen bond in aryl and vinyl halides are unusually shorter. Reason (R): Chlorobenzene and vinyl chlorides undergo $S_N1$ and $S_N2$ reaction in general.

Assertion (A): Enantiomers are inseparable on simple column chromatography. Reason (R): Enantiomers bind achiral stationary phase with equal affinity and Enantiomers can be separated by using chiral stationary phase.

Assertion (A): In $S_N1$ reaction racemic mixture is formed and in $S_N2$ reaction inversion of configuration is observed. Reason (R): $S_N1$ reaction is concerted mechanism and $S_N2$ reaction involves carbocation intermediate.

Match List - I (Compounds) with List - II (Applications): (A) Silicones, (B) Boranzines, (C) Phosphazenes, (D) Poly siloxanes

For Schrodinger Wave Equation $\nabla^{2}\psi+\frac{8\pi^{2}m}{h^{2}}(E-V)\psi=0$, an acceptable solution does NOT possess which of the following property?}

Assertion (A): In $[Ti(H_{2}O)_{6}]^{3+}$ electronic spectra the observed absorption is unsymmetrical appears to be result of more than one absorption bands. Reason (R): Due to Jahn Teller effect energy of $d_{xy}$ is lowered so shown electronic jump $d_{xy}^{1} \rightarrow d_{x^{2}-y^{2}}$ and $d_{xy}^{1} \rightarrow d_{z^{2}}$ so give rise two absorption bands.}

Match List - I (Compounds) with List - II (Hybridization and no. of L.P.): (A) $SF_{4}$, (B) $ClF_{3}$, (C) $H_{2}O$, (D) $NH_{3}$}

Assertion (A): In $B_{2}H_{6}$, two bridging H atoms prevent the rotation between B atoms. Reason (R): Terminal B-H bonds are normal covalent bonds i.e. two centre two electron ($2C-2e$) bonds.}
