#define MASK(y) (1 << y % CHARSIZE)

#define BITSLOT (y) (y / CHARSIZE)

#define SET(x,y) ( x[BITSLOT(y)] = MASK(y) )

#define TEST(x,y) ( x[BITSLOT(y)] & MASK(y) )

#define NUMSLOTS(n) ((n + CHARSIZE - 1) / CHARSIZE)

 

Give the above macros how would you

1. declare an array arr of 50 bits

2. put the 20th bit on

3. test whether the 40th bit is on or off

Answer

1. char arr[NUMSLOTS(50)];

Q:

Which of the following chemical compounds has the highest boiling point?

A) Dimethyl ether (CH3OCH3) B) Methanol (CH3OH)
C) Methane (CH4) D) None
 
Answer & Explanation Answer: B) Methanol (CH3OH)

Explanation:

Chemical Compounds with stronger intermolecular forces have higher boiling points.

 

The order of strengths of intermolecular forces is:

 London dispersion < dipole-dipole < H-bonding

 

Methane (CH4) — London dispersion forces

Dimethyl ether (CH3OCH3) — dipole-dipole attractions

Methanol (CH3OH) — hydrogen bonding

Therefore, Methanol - CH3OH with H-Bonding have highest Boiling Point among the given chemical compounds.
