While the other pairs, sodium and potassium are the metals, nitrogen and iodine, chlorine and bromine, helium and oxygen are the non-metals. They do not form ionic bond. Hence, the correct pairs of elements likely to form ionic compounds are, potassium and sulfur, magnesium and chlorine
Answer:
1) 2-bromobutane
2) 1-bromobutane
Explanation:
In the HBr reaction, we will have a <u>markovniknov reaction</u> due to the <u>carbocation formation</u>. The Br- then would be added in the <u>most substituted</u> carbon of the double bond.
In the HBr/peroxide reaction we have the opposite case: an <u>anti-markovnikov reaction</u>. Therefore the Br- would be added in the <u>least substitued</u> carbon of the double bond.
D. Sometimes it is necessary to put forth new theories to explain experimental results,
Explanation:
Creativity is important to science because sometimes, it is necessary to put forth new theories to explain experimental results.
Theories are explanation of scientific observations.
- Most scientists are critical and creative thinkers.
- They must be able to come up with a wide range of possible explanation to explain their findings.
- The explanations must be scientific in nature and not fall out of the basic tenets of this way of thinking.
- Therefore, scientists draw from their wealth of deductive reasoning to give explanations into an observed phenomenon.
