The major group of organic chemicals that has double the number of hydrogen atoms as carbon or oxygen atoms [chemical formula (ch2o)n] is carbohydrates.
<h3>What are carbohydrates?</h3>
Carbohydrates are biological macromolecules that function as macronutrients by providing energy, which are composed of simple carbon-based molecules linked by glycosidic bonds.
In conclusion, the major group of organic chemicals that has double the number of hydrogen atoms as carbon or oxygen atoms [chemical formula (ch2o)n] is carbohydrates.

Answer:
Neopentane (C(CH3)4) have a lower a lower boiling point than n-pentane (CH3CH2CH2CH2CH3) because of it branched chain.
Explanation:
Structural isomers are compounds that have the same molecular or chemical formula but have different arrangement of atoms in space. The connectivity of the atoms differs for this compounds but they possess the same molecular formula. An example of structural isomers are butane and methyl propane. Usually, as the number of carbon increases for alkane the number of isomers also increases.
Since Isomers are different compound they are bound to have different characteristic both in melting and boiling points. Generally, straight chained isomers have higher boiling points than branched chain isomers.
n-pentane (CH3CH2CH2CH2CH3) is a straight chained isomer while neopentane (C(CH3)4) is a branched chain isomer. Neopentane (C(CH3)4) have a lower a lower boiling point than n-pentane (CH3CH2CH2CH2CH3) because of it branched chain.
Answer:
Br- Withdraws electrons inductively
Donates electrons by resonance
CH2CH3 - Donates electrons by hyperconjugation
NHCH3- Withdraws electrons inductively
Donates electrons by resonance
OCH3 - Withdraws electrons inductively
Donates electrons by resonance
+N(CH3)3 - Withdraws electrons inductively
Explanation:
A chemical moiety may withdraw or donate electrons by resonance or inductive effect.
Halogens are electronegative elements hence they withdraw electrons by inductive effect. However, they also contain lone pairs so the can donate electrons by resonance.
Alkyl groups donate electrons by hyperconjugation involving hydrogen atoms.
-NHCH3 and contain species that have lone pair of electrons which can be donated by resonance. Also, the nitrogen and oxygen atoms are very electron withdrawing making the carbon atom to have a -I inductive effect.
+N(CH3)3 have no lone pair and is strongly electron withdrawing by inductive effects.
Umm i don’t get it, is it a joke?
Moles XeF6 = 10.0g/ 245.28 g/ mol=0.0408
The ratio between F2 and XeF6 is 3:1
Moles F2 required = 3 x 0.0408=0.122
Mass F2 = 0.122 mol x 37.9968 g/ mol=4.64g
