The correct answer is statement 3, the difference in electronegativity between carbon and oxygen is greater than that between fluorine and oxygen. The most polar bond is the one with the highest difference in electronegativity values between two atoms. In this case, the C-O bond.

Answer: (3) The difference in electronegativity between  carbon and oxygen is greater than that  between fluorine and oxygen.

Explanation: Polarity of a molecule is due to the difference in electronegativity of the atoms. More is the electronegativity difference, more is the polarity.

Electronegativity of carbon = 2.5

Electronegativity of oxygen = 3.5

Electronegativity of fluorine = 4.0

Thus the difference in electronegativity of carbon and oxygen is=(3.5-2.5)= 1.0

Thus the difference in electronegativity of fluorine and oxygen is=(4.0-3.5)= 0.5.

Thus C-O bond is more polar than F-O bond.

A student practicing for a track meet ran 300 meters in 30 seconds. what was her average speed?​
ololo11 [35]

Answer:

<h2>10 m/s</h2>

Explanation:

Her average speed can be found by using the formula

v =  \frac{d}{t}  \\

d is the distance

t is the time taken

From the question we have

v =  \frac{300}{30}  = 10 \\

We have the final answer as

<h3>10 m/s</h3>

Hope this helps you

How many monochlorination products can be formed (constitutional isomers only) from the reaction of (CH3)2CHCH2CH3 with Cl2 and
faltersainse [42]

Answer:

4 monochlorination products can be formed.

Explanation:

Constitutional isomers : These are those compounds with same molecular formula but different atomic arrangement.For example: butane and 2-methly-propane.

On monochlorination of 2 methyl-butane  we will have four possibilities of product which will be constitutional isomers of each other:

  • 1-chloro-3-methyl butane : (CH_3)_2CH-CH_2-CH_2-Cl
  • 2-chloro-3-methyl butane : (CH_3)_2CH-CHCl-CH_3
  • 2-chloro-2-methyl butane (CH_3)_2CCl-CH_2-CH_3
  • 1-chloro-2-methyl butane (CH_2Cl)_2CH-CH_2-CH_3

Two identical balloons are inflated to a volume of 1.00 L with a particular gas. After 12 hours, the volume of one balloon has d
ratelena [41]

Answer:

43.7

Explanation:

Volume of gas = 1.00L

Time = 12 hours

Decrease in 1 balloon = 0.200L

Decrease in second balloon = 0.0603L

R1 = rate at which helium diffuses= 0.20/12= 0.0166

R2 = rate at which heavier gas diffuses = 0.0693/12 = 0.00502

Using grahms law

R1²/R2² = m/4

= 0.0166²/0.00502² = m/4

= 10.935 = m/4

When we cross multiply

m is the molar mass of heavier gas = 43.73
