Answer:
Noble gases are a set of elements in the periodic table because they don't naturally bond with other elements. *Examples ...Helium; Neon; Radon; Xenon; Argon etc
Explanation:
theyre noble gases.
Answer:
3 significant digits
Explanation:
The first 0 don't count (that's the rule in significant digits). So 3,0,0 are left over. Count them and total will be 3 significant digits. (remember the last zero count if there is a decimal but the first zeros doesn't count even with the decimals)
Answer:
2672 kj
Explanation:
C4H10 O mole wt = 48 + 10 + 16 =~ 74 gm
27200 gm / 74 gm/mole = 367.57 moles
367.57 moles * 7.27 kj/mole =
Answer:
Correct option : "The mechanism results in a carbocation rearrangement in which a methyl shift occurs"
Explanation:
In the first step, 2,2-dimethyl-1-propanol gets protonated.
In the second step, a carbocationic intermediate is produced from removal of 
.
In the third step, shifting of methyl group occurs to produce more stable carbocationic intermediate.
In the fourth step, 
attacks the stable carbocation to produce 2-bromo-2-methylbutane.
So, correct option : "The mechanism results in a carbocation rearrangement in which a methyl shift occurs"
Full reaction mechanism has been shown below.
Explanation:
(a) CH₄
The molecule of methane is non polar in nature , hence it will show only the dispersion forces .
(b) NO₂
The molecule of nitrogen dioxide will show both dipole-dipole interactions and dispersion forces as well .
Since , the molecule is has an electronegative atom , i.e. , oxygen , so will show dipole - dipole interactions .
(c) SO₂
The molecule of sulfur dioxide will show both dipole-dipole interactions and dispersion forces as well .
Since , the molecule is has an electronegative atom , i.e. , oxygen , so will show dipole - dipole interactions .
