Hydrolysis of Organic Compound

My thought process with this was: The ether wala O recieved H+, bond is broken between the left end and the O atom, the left part recieves an O atom and then forms acetal with the keton group. Is this correct? Also how to approach?

+M or Leaving ability?

answer is D have 2 logics: 1. NH2 has strong +M and Cl has stong +I but i dont think Cl ka +I can be more than NH2 ka +M 2. NH2 wont leave very easily since its more bulky and Cl will leave easily, thus giving a higher yield ...

Chemical Bonding

I don't think they're all 0 cause well this is a JEE question xd. I saw something online saying O--H bond is rotatable so dipole moment is non-zero but I dont understand it fully

Integral, trig

$\int_{ }^{ }\frac{\left(\sin x+\cos x\right)}{\sqrt{\sin\left(2x\right)}}$

ITF simplification

Express $\tan^{-1}\left(\frac{\cos x}{1-\sin x}\right),\ \ -\frac{3\pi}{2}<x<\frac{\pi}{2}$ in the simplest form.

my idea of limits is very poor but why is limit x tends to 0 [x sin(1/x)] 0?

i can write it as [sin (1/x)]/(1/x) , will the ' limit x-0 sinx/x=1 ' work?
