A) Distillation B) Cooling
C) Drilling D) Cracking
 
Answer & Explanation Answer: A) Distillation

Explanation:

The first step in the refining of petroleum is distillation i.e,  the fractionation of crude oil in atmospheric and vacuum distillation towers.

The first process petroleum refinery is known as distillation. In this process, crude oil is heated and fed into a distillation column. As the temperature of the crude oil in the distillation column rises, the crude oil separates itself into different components, called "fractions." The fractions are then captured separately. Each fraction corresponds to a different type of petroleum product, depending on the temperature at which that fraction boils off the crude oil mixture.

What do the functions atoi(), itoa() and gcvt () do? Show how would you use them in a program.

Answer

atoi()         Converts a string to an integer.


itoa()         Convert an integer to a string


gcvt()        Converts a floating-point number to a string


 


#include "stdlib.h"


main()


{


      char s[] = "12345";


      char buffer [15], string[20];


      int i;


      


      i = atoi (s);


      printf("\n%d",i);


 


       gcvt (20.141672, 4, buffer);


       printf ("\n%s", buffer);


 


       itoa(15, string,2);


        printf ("\n%s", string);


}

Q:

Order of basicity of amines in gaseous state?

A) 2'> 1'> 3' > NH3 B) 3' > 2' > 1'> NH3
C) 1' > 2' > 3'> NH3 D) 2'> 3'> 1' > NH3
 
Answer & Explanation Answer: B) 3' > 2' > 1'> NH3

Explanation:

The order of basicity in ammonia is different in gaseous phases vs. aqueous phases due to hydrogen bonding.

 

So in gaseous phases it's the well known: 3' > 2' > 1'> NH3. Just so we're on the same page, this is due to the inductive effect of electron donating alkyl groups--they destabilize the lone pair on nitrogen atom, making nitrogen more basic.

 

But in aqueous phase, the order is slightly different: 2'> 1'> 3' > NH3.
