All About Elimination Reactions of Alcohols (With Acid) The hydroxyl group of alcohols is normally a poor leaving group. However, when treated with strong acid, R-OH is converted into R-OH2(+) and H2O is a much better leaving group. With tertiary alcohols, H2O can then leave, resulting in a carbocation. If a strong acid such as H2SO4 or p-TsOH is used, the most likely result is elimination, since the conjugate bases of these ... Xem chi tiết

Why is the Synchronous Motor Not Self Starting?
Why are Synchronous Motor and Synchronous Machines Not Self Starting? We know that a synchronous motor is not a self starting machine. This is because when the armature (stator) of the synchronous motor is connected to the three phase supply, a rotating magnetic field is produced in it which rotates at synchronous speed while the rotor is in static position. When the static field poles of the rotor are excited through an ... Xem chi tiết

Transpiration is defined as the physiological loss of water in the form of water vapor, mainly from the stomata in leaves, but also through evaporation from the surfaces of leaves, flowers, and stems. There are three main types of transpiration, based on where the process occurs: Stomatal ... Xem chi tiết

Concepts of Biology – 1st Canadian Edition
For more complex organisms, diffusion is not efficient for cycling gases, nutrients, and waste effectively through the body; therefore, more complex circulatory systems evolved. Most arthropods and many mollusks have open circulatory systems. In an open system, an elongated beating heart pushes the hemolymph through the body and muscle contractions help to move fluids. The larger more complex crustaceans, including lobsters, ... Xem chi tiết
