122g/58.44g/mol = 2.088mol
Explanation:
In normal atmosphere, analytical reagents may absorb water molecules that may affect the results of chemical reactions. So, in order to get accurate results from these analytical regents, they must be stored in a dessicated atmosphere or heated before being used so that the water molecules must dry away.
Answer:
CH3O- , OH-, NH-2
Explanation:
The given nucleophilic compounds:
Hydroxide, OH-, Ammonia, NH3, Water, H2O, Methanol, CH3OH, Methoxide, CH3O-, Cyanide, CN-, Amide, NH2-
<u>Nucleophile capable for doing E2reaction:
</u>
Generally strong basic compounds are used for E2- Elimination. Because in E2 - elimination proton abstraction and leaving group leaving happen on same time so we need strong base for E2-elimination.
In the given compounds only CH3O- , OH-, NH-2, are strong basic compounds so these compounds only capable for doing E2-Elimination.
Ethene belongs to class of
unsaturated hydrocarbons called as
Alkenes. Alkene contains a
double bond between two carbon atoms. And the general formula for alkene is,
CnH2nWhereas in Ethene, n = 2, so
C₂H₄
Therefore, in ethene there are two carbon atoms doubly bonded to each other via
one sigma and
one pi bond. Also each carbon atom is further covalently bonded to
two hydrogen atoms via sigma bond as shown below,
Answer:
B
Explanation:
Valence electrons only involve in chemical bonding, since they are farthest from the nucleus. Hope this helps!
