Chemistry: Post your doubts here!
The intermediate for W: CH3CHCH3+ (Hydrogen is lost from central carbon ) X: CH3C(OH)CH3+ (Hydrogen is lost from central carbon) Y:CH3CHCH3+ (Hydrogen is ADDED to Ch2 due to markonikov's rule) Z:CH3CH2CH2OH (Alcohol from ester hydrolysis) So W and Y have the same intermediates! hope this... -

Yo, listen, you confused it with hydrolysis of ester with dilute Sodium Hydroxide which does result in a sodium salt of carboxyllic acid and the alcohol! :) -

you want to find out when you will get the same length of amplitude as y1, so in this case Y1 MUST BE POSITIVE, and the same amplitude will thus occur one wavelength later as two points on a single transverse wave with the same phase difference will have the SAME AMPLITUDE (length from the... -

q.29 the distance between two adjacent antinodes(maxima) in a stationary wave is 1/2 lamda, so 1 lambda is 1.5cm * 2= 3cm= 0.03m f=v/lamda (wave equation) v= 3.00*10^8 (given in first pg of exam paper) (microwave is light) 3.00*10^8 / 0.03 = 1*10^10 which is C -
