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.
Violet, indigo, blue, green, yellow, orange, red
Answer:
the answer is nitrogen and rubidium (C)
Explanation:
ionic bonds only form between metals and non-metals
<span>The effective method for separating a mixture of alcohol and water is the
Distillation
</span> By this you only get about 70% alcohol 30% water
As they are <span>azeotropes and cannot be distilled further
so correct option is B
hope it helps

Answer:
C: Carbon monoxide - Acidic nature
Explanation:
A) Beryllium is not soluble in water but yet it reacts with an acid and a base. Therefore, since it exhibits both basic and acidic nature, we say it is Amphoteric in nature. Thus it is correct
B)potassium super oxide has the formula KO2. It reacts with acid to form salt called potassium chloride. Thus, it is basic in nature.
C) Carbon monoxide does not react with acids or bases. Thus, it doesn't show either an acidic or basic property and we say it is a neutral oxide. This option is incorrect
D) Bismuth oxide is a basic oxide because it displays properties of a base. This options is correct
