Chemistry QUESTION #1446

Question 5422

Which reaction involves the conversion of aldehydes into alcohols?

Oxidation
Reduction✔️
Hydrolysis
None of these

Correct Answer Logic:

Aldehydes ($RCHO$) are converted to primary alcohols ($RCH_2OH$) by reduction — adding hydrogen across the $C=O$ bond. Common reducing agents include $\text{NaBH}_4$ (sodium borohydride) and $\text{LiAlH}_4$ (lithium aluminium hydride). Oxidation of aldehydes gives carboxylic acids, not alcohols. Hydrolysis is for esters, amides, etc.

Question 5423

Higher yield of NO in $\text{N}_2(\text{g})+\text{O}_2(\text{g})\rightleftharpoons 2\text{NO}(\text{g})$, $\Delta H=+180.7\ \text{kJ mol}^{-1}$:

B, C, D only
A, C, D only✔️
A, D only
B, C only

Correct Answer Logic:

Reaction is endothermic ($\Delta H>0$). By Le Chatelier's principle: (A) Higher temperature shifts equilibrium forward (endothermic) → higher NO yield ✓. (B) Lower temperature shifts backward → less NO ✗. (C) Higher [N$_2$] shifts equilibrium forward → more NO ✓. (D) Higher [O$_2$] shifts equilibrium forward → more NO ✓. Correct: A, C, D = option (2).

Statistics QUESTION #1965

Question 5426

An ordinal (ranking) scale inherently includes all properties of which other measurement scale?

Nominal scale✔️
Interval scale
Ratio scale
All of the above

Correct Answer Logic:

An ordinal scale includes the classification property of the nominal scale, and adds ordering. Hence it always includes all properties of the nominal scale.

Mathematics QUESTION #6037

Question 5430

Find a value of $\theta$ for which $\dfrac{2+3i\sin\theta}{1-2i\sin\theta}$ is purely imaginary.

$\dfrac{\pi}{6}$
$\sin^{-1}\!\left(\dfrac{\sqrt{3}}{4}\right)$
$\sin^{-1}\!\left(\dfrac{1}{\sqrt{3}}\right)$✔️
$\dfrac{\pi}{3}$

Correct Answer Logic:

Multiply numerator and denominator by the conjugate of the denominator $(1+2i\sin\theta)$:

Numerator real part: $(2+3i\sin\theta)(1+2i\sin\theta)$ real part $= 2-6\sin^2\theta$

For purely imaginary, the real part must be zero: $2-6\sin^2\theta=0\Rightarrow\sin^2\theta=\frac{1}{3}\Rightarrow\sin\theta=\frac{1}{\sqrt{3}}$

Therefore $\theta=\sin^{-1}\!\left(\dfrac{1}{\sqrt{3}}\right)$

Chemistry QUESTION #1418

Question 5435

A zero-order reaction rate does not depend on:

Temperature
Pressure
Reactant concentration✔️
None of these

Correct Answer Logic:

For a zero-order reaction, the rate law is: $\text{rate} = k[\text{A}]^0 = k$. The rate is equal to the rate constant $k$ and is independent of the concentration of reactants. However, the rate constant $k$ itself depends on temperature (via the Arrhenius equation), so temperature does affect the rate — but concentration does not.

Question 5437

For $f(x,y)=xy-2x$ on the triangular region with vertices $(0,0)$, $(4,0)$, $(0,4)$, the absolute minimum value is:

$-8$✔️
$0$
$-4$
$4$

Correct Answer Logic:

On boundary edge from $(0,0)$ to $(4,0)$ ($y=0$): $f=-2x$, minimum at $x=4$: $f=-8$. Interior critical point: $f_x=y-2=0\Rightarrow y=2$; $f_y=x=0\Rightarrow x=0$, giving $f(0,2)=0$. Checking all boundaries, the absolute minimum is $-8$ at $(4,0)$.

Question 5439

A subgroup $H$ of a group $G$ is called normal if for all $g\in G$:

gH=H
gHg^{-1}\subseteq H✔️
H contains the identity
H is abelian

Correct Answer Logic:

A subgroup $H$ is normal in $G$ if $gHg^{-1}=H$ (equivalently $gHg^{-1}\subseteq H$) for all $g\in G$. This means left and right cosets coincide: $gH=Hg$ for all $g\in G$. Normal subgroups are the kernels of homomorphisms.
