Chemistry QUESTION #5572

Question 602

What is the major product when $R-C\equiv N$ is treated with (1) $AlH(i-Bu)_2$ (DIBAL-H), then (2) $H_2O$?

RCOOH
$RCONH_2$
RCHO✔️
$RCH_2NH_2$

Correct Answer Logic:

DIBAL-H (diisobutylaluminium hydride) at low temperature partially reduces a nitrile ($RC\equiv N$) to an imine intermediate ($RCH=NH$), which upon aqueous workup ($H_2O$) hydrolyses to give an aldehyde (RCHO). Full reduction with $LiAlH_4$ would give the amine $RCH_2NH_2$.

Physics QUESTION #7079

Question 612

Determine the pressure required at the ends of a steel wire (length $10\text{ cm}$) to maintain a constant length when the temperature is increased by $100^{\circ}\text{C}$. (Given: Steel Young's modulus $Y = 2 \times 10^{11}\text{ Nm}^{-2}$ and coefficient of thermal expansion $\alpha = 1.1 \times 10^{-5}\text{ K}^{-1}$)

$2.2 \times 10^{7}\text{ Pa}$
$2.2 \times 10^{6}\text{ Pa}$
$2.2 \times 10^{8}\text{ Pa}$✔️
$2.2 \times 10^{9}\text{ Pa}$

Correct Answer Logic:

The thermal stress required to keep the length constant is given by the formula:

$\text{Stress} = Y \alpha \Delta T$
Substituting the values: $\text{Stress} = (2 \times 10^{11}) \times (1.1 \times 10^{-5}) \times 100$
$\text{Stress} = 2.2 \times 10^{8}\text{ Pa}$

Pressure is equivalent to the stress applied at the ends.

Physics QUESTION #7091

Question 613

Guns A and B fire bullets at $1\text{ km/s}$ and $2\text{ km/s}$. Find the ratio of the maximum areas covered on the ground.

1:16✔️
1:02
1:04
1:08

Correct Answer Logic:

The maximum range is $R_{max} = \frac{u^2}{g}$.

Area covered is a circle: $A = \pi R_{max}^2 = \pi (\frac{u^2}{g})^2 \propto u^4$.
Ratio: $\frac{A_1}{A_2} = (\frac{u_1}{u_2})^4 = (\frac{1}{2})^4 = 1:16$.
