Williamson ether synthesis is an organic reaction, forming an ether from an organohalide anda deprotonated alcohol(alkoxide). It involves the reaction of an alkoxide ion with a primary alky halide via SN2 reaction. The reaction to form propoxypropane using Williamson reaction is as shown
CH3CH2CHONa + CH3CH2CH2Br = C2H5CH2-O-CH2C2H5 + NaBr
Sodium propoxide 1-Bromopropane 1- Propoxypropane
Answer: B) k
Explanation:
potassium is an intracellular cation.
In resting state its gated channels are shut; so 95% are trapped inside the interstitial fluids of the axoplasm;Although these channels leak for some to escape down the concentration gradient to the extracellular environments of the axon, most of these ion are concentrated inside the interstitial fluid of the axon to maintain RMP
I t can tell you a if something is a multicellular cell or if it isn't a multicellular cell because you might get a different discovery every time you look at a stem cell
The area namely Tundra receives least amount of precipitation, i.e., option C.
<h3>What is a biome?</h3>
A distinctive biogeographical unit built by a biological community in response to a shared regional environment. Biomes can exist on multiple continents.
