`PCl_(3)` and an alcohol can react in `x:y` molar ratio to form corresponding alkyl halide and an oxyacid of basicity `z`. What is `(y/x+z)`?

X' is a smallest optically active alkanol. On dehydration it can form Y number of alkenes (including stereoisomers). On reaction with Lucas reagent it forms Z number of alkyl halides (including stereoisomers). Report your answer as ZY.

An alkyl halide (X) on reaction with ethanolic sodium hydroxide forms an alkene (Y) which on further reaction with HBr gives the same alkyl halide.The alkene (Y) on reaction with HBr/ peroxide followed by reaction with Mg metal followed by reaction with HCN produces an aldehyde (Z).Z is :

Primary alkyl halide C_4H_9Br (X) reacts with alc. KOH to give compound (Y). (Y) reacts with HBr to give compound (Z) which is an isomer of (X). When (X) reacts with Na metal it gives compound (P). (X), (Y), (Z) and (P) are

If x and y be unequal and x : y is the duplicate ratio of x + z and y + z , prove that z is Mean proportional between x and y .

The averge of x and 3y is 12, the average of 2x and 3z is 21. What is the average of x,y and z ?

Assume that neither x nor y is equal to 0, to permit division by x and by y. What is the ratio x:y:z ? (1) x+y=2z (2) 2x+3y=z

Find the equation of line x+y-z-3=0=2x+3y+z+4 in symmetric form. Find the direction ratio of the line.

A metal X reacts with aqueous NaOH solution to form Y and a highly inflammalbe gas. Solution Y is heated and CO_(2) is poured through it. Z precipitates out and Na_(2)CO_(3) is formed. Z on the heating gives AI_(2)O_(3) . Identify X,Y and Z. X Y Z

The symmetric form of the equation of the line x + y-z =3, 2x+3y+ z+4=0 is :
