Remember velocity = distance/time so that mean you would do 60/3 which equals 20 so the speed(velocity) equals 20
Answer:
The correct answer is (D) All of the above.
Explanation:
A chemical bond is the attraction force between atoms (covalent bond) or between oppositely charged ions (ionic bond) to form a stable arrangement. In order to get a stable arrangement must be fulfilled the octet rule. This establishes that an atom could share (covalent bond) win or lose (ionic bond) electrons with other atoms till every atom has eight valence electrons. The complete outer shell of valence electrons make elements stable to get a stable noble gas configuration.
Answer:
The IHD = 0
There is no unsaturation in the compound C4H9Cl
Explanation:
IHD = Index for Hydrogen Deficiency .It determines total number of unsaturation or Pi- bond present in the molecule.It is calculated using the formula:
For Molecule:
![C_{c}H_{h}O_{o}N_{n}X_{x}](https://tex.z-dn.net/?f=C_%7Bc%7DH_%7Bh%7DO_%7Bo%7DN_%7Bn%7DX_%7Bx%7D)
Here . C = carbon
H = Hydrogen
O = Oxygen
N = Nitrogen
X = Halogen
The IHD is calculated as :
...............(1)
For example :
C4H8O2
Here c = 4 , h = 8 , o = 2 .
n = x=0
Put the value in equation (1) and find IHD
![\frac{2(4)-8-0+0+2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%284%29-8-0%2B0%2B2%7D%7B2%7D)
![\frac{8-8+2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B8-8%2B2%7D%7B2%7D)
![\frac{2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B2%7D)
IHD = 1
For C4H9Cl
c = 4 , h = 9 and x = 1
IHD for this molecule can be calculated as :
![\frac{2c-h-x+n+2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2c-h-x%2Bn%2B2%7D%7B2%7D)
![\frac{2(4)-9-1+2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B2%284%29-9-1%2B2%7D%7B2%7D)
![\frac{8-9-1+2}{2}](https://tex.z-dn.net/?f=%5Cfrac%7B8-9-1%2B2%7D%7B2%7D)
= 0
This means there is no unsaturation in the molecule.
Each bond is sigma bond and properly saturated.
