Q.,Explain the following as used in medicinal chemistry (a) Lead compounds(b) Target molecules or drug targets. |
|
Answer» In medicine, a chemical compound that shows promise as a treatment for a disease and may lead to the development of a new drug. THOUSANDS of compounds are tested in the laboratory to find a lead (“leading”) compound that may act on specific genes or proteins involved in a disease In medicinal CHEMISTRY, target MOLECULES or drug targets refer to the key molecules (such as carbohydrates, proteins, and nucleic acids) that are involved in certain metabolic pathways leading to certain DISEASES. These target molecules are INHIBITED when the drug molecules bind to the active sites. |

Compare the shapes of trialkyl carbocation and trialkyl carbanion. |
| Answer» CARBOCATION and carbanion are two TERMS that are frequently used in organic chemistry. These are organic chemical SPECIES bearing an electrical charge on a carbon atom. Carbocations and carbanions are often found as intermediates of some REACTIONS. The main difference between carbocation and carbanion is that carbocation CONTAINS a carbon atom bearing a positive charge whereas carbanion contains a carbon atom bearing a negative charge.Explanation:hope it helps you | |

Name the two laws of chemical combination and write the statement of each of them. |
|
Answer» LAWS OF CHEMICAL COMBINATION consist of two laws: The law of the CONSERVATION of mass, in which mass before REACTION has to equal mass after reaction. The law of constant proportions, in which the ratio mass for the same compound is constant. The law of multiple proportions, in which multiple ELEMENTS can combine with each other in multiple ratios; and finally. eg: ratio of 1:8 of hydrogen to oxygen in WATER.

During the process of condensation Kinetic Energy of particles will A) Decrease B) Increase C) Remain constant D) Neither increases nor decreases |
|
Answer» Does kinetic energy increase or decrease during condensation?Condensation is the changing of a gas to a liquid. The VAPOR molecules give up so MUCH kinetic energy that they can't stay in the gaseous phase. The molecules BEGIN to stick together or condense. Kinetic energy lost by condensing gas molecules warms the surface they strike.hope it helps you ✌ |

Answer» In physics, a state of MATTER is one of the distinct forms in which matter can exist. FOUR states of matter are observable in everyday life: solid, liquid, gas, and plasma. Many INTERMEDIATE states are known to exist, such as liquid CRYSTAL, and some states only exist under extreme conditions, such as Bose–Einstein condensates, neutron-degenerate matter, and quark–gluon plasma, which only occur, respectively, in situations of extreme cold, extreme density, and extremely high energy.

Newlands' Law of Octaves The English scientist John Newlandscorrelated the atomic masses of elementsto their properties in a diffrent way in theyear 1866 Newlands arranged the elementsknown at that time in an increasing orderof their atomic masses. t started with thelightest element hydrogen and ended upwith thorium. He found that every eighthelement had properties similar to those ofthe first. For example, sodium is the eighthelement from lithium and both have similarproperties. Also, magnesium showssimilarity to beryllium and chlorine showssimilarity with fluorine. Newlandscompared this similarity with the octavesin music. He called the similarity observedin the eighth and the first element as theLaw of octaves. 1 .Create questions on this paragraph and also write the answers |

What is slab how it is separated from the metal |
|
Answer» Slabs are constructed to provide flat surfaces, usually horizontal in building floors, roofs, bridges, and other types of STRUCTURES. The slab may be supported by walls or by reinforced concrete beams usually CAST monolithically with the slab or by structural steel beams or by columns, or by the ground.Concrete generally has reinforcing steel rods embedded in it and during the crushing process the steel is broken into short lengths with very SHARP points. The steel has to be removed before the concrete can be reused and the most efficient method of RECOVERING the steel is through magnetic separators.follow, thank and mark me BRAINLIEST |
