Answer:
The last figure (with the name 3-Chloro-2-iodo-4-methylhexane) is correct.
Explanation:
---> It gives the correct numbering of the positions of each Iodine Chlorine and Methyl which are attached at 2, 3 and 4 respectively
---> and also the names are given on alphabetical order (i.e. first Chlorine then Iodine and then Methyl)
That would be exothermic. Exothermic reactions are processes that release energy, usually in the form of heat or light. Energy is released because the total energy of the products is less than the total energy of the reactants.
Answer:
false
Explanation:
in 1869 Dimitri Mendeleev a Russian chemist development the periodic table arranging elements by atomic mass
Answer:
Substances with high boiling points condense at the bottom and substances with lower boiling points condense on the way to the top. The crude oil is evaporated and its vapours condense at different temperatures in the fractionating column.
Explanation:
answer above
None of the given statements are completely true.
<u>Explanation</u>:
Family or groups in "periodic table" are 18 in number which represents column in table. As we go down in a family or group in the "periodic table"-the atom size become bigger and bigger. Non-Metals are less reactive which mostly lie in p-block. "Metals" are ""ore reactive" in "s-block". The atom’s valence electrons remain same for example when we go down in alkali metals in s-block the valence electron is one only and in alkaline earth metals its two only.
