Answer & Explanation Answer: B) Paraffin > Octadecane > Hexane > Neohexane > Ethane

Explanation:

In hydrocarbon, the boiling point directly varies with the length of carbon chain. On increasing the number of carbon atom, the boiling point of the compound also increases. Paraffin contains highest number of carbon atoms whereas, ethane is comprised of two carbon atoms.

 

The decreasing order of boiling point of mention compounds is written as follows:

Paraffin > Octadecane > Hexane > Neohexane > Ethane

Q:

At 3.40, the hour hand and the minute hand of a clock form an angle of:

A) 120 degrees B) 125 degrees
C) 130 degrees D) 135 degrees
 
Answer & Explanation Answer: C) 130 degrees

Explanation:

Angle traced by hour hand in 12 hrs. = 360º.

 

Angle traced by it in  11/3 hrs=  36012*113°=110°

 

Angle traced by minute hand in 60 min. = 360º.

 

Angle traced by it in 40 min. =(360/60*40)°=240°

 

  Required angle (240 - 110)º = 130º.

A) 40 B) 44
C) 60 D) 56
 
Answer & Explanation Answer: A) 40

Explanation:

The given puzzle follows a logic that,

2 + 10 = 24 => 2 + 10 = 12 x 2 = 24

3 + 6 = 27 => 3 + 6 = 9 x 3 = 27

7 + 2 = 63 = 7 + 2 = 9 x 7 = 63

 

Similarly, 5 + 3 = 40 => 5 + 3 = 8 x 5 = 40.
