Question

Write the molecular formulae of the following:
a) 2-Butanol
​

Answer 1

Answer:

the molecular formula for 2 butanol is (74.122gm)or mol is the unit

the chemical formula is c4H10

Answer 2

Answer:

butanol

Step-by-step explanation:

• the root word is 'but which means it consist 4 carbon
• next it is alkane which means it is single bond
• it has the functional grp 'ol' which is alcohol

therefore the molecular formula is

CH3 - CH2 - CH2 - CH2 -OH

C4 H10 O

since the question is 2 butanol

CH3 - CH - CH2 - CH3

|

OH

2butanol means the functional grp must be placed in the 2 place
