the electron in benzene are delocalised making d ring to be elctron rich,thereby undergoing electrophilic substitution.benzene cannot undergo nucleophillic substitution,it can only undergo if it is substituted with an electron withdrawing group

Hypersecretion of glucocorticoids, such as cortisol, can lead to conditions like Cushing's syndrome. Symptoms may include weight gain, particularly in the trunk and face, high blood pressure, muscle weakness, and mood changes. It can also suppress the immune system and affect metabolism.

the cartographer is both a scientist and an artist.he must have a through knowledge of his subject and model,the Earth.in representing it in different ways he must omit more or less,according to the scale and purpose of his map.this means that he must have the ability to generalize intelligently and to make a correct selection of the essential features to be shown.these features are represented by lines, patterns,and colours,the effective use of which requires more than knowledgeof the subject-it requires artistic judgement

The cation formed upon addition of an electrophile to benzene is highly stabilized by resonance,whereas the cation formed to an alkene is stabilized by hyperconjugation. The loss of a proton in benzene is favourable due to the restoration of the cyclic pi-system.

The B.Ed syllabus in Tamil Nadu typically includes foundational papers on education, curriculum and pedagogy, educational psychology, and research methodology. Specialization papers may cover topics such as language education, mathematics education, science education, and social studies education. Additionally, there are practical components like teaching practice and school internship. You can check with the specific university or college for detailed information on the syllabus.

Phenol undergoes electrophilic substitution reactions due to the presence of the highly electronegative oxygen atom in the phenolic ring, which can stabilize positive charge through resonance. This makes the phenolic ring more susceptible to attack by electrophiles, leading to substitution reactions.

Substances that are polar or ionic in nature are generally soluble in water, as water is a polar solvent. Nonpolar substances, such as fats and oils, are typically insoluble in water but may dissolve in nonpolar solvents like oil or hexane.

During Wegener's time, modern clues such as advancements in technology and research methods were not available. Additionally, the scientific community at that time did not widely accept the theory of continental drift proposed by Wegener, which limited the exploration and investigation of supporting evidence.

Benzene predominantly undergoes electrophilic reactions because its aromatic structure stabilizes the developing positive charge on the carbon atoms during the reaction. The delocalized electron cloud in benzene makes it less reactive towards nucleophiles which prefer to attack electrophilic centers. This electronic stability of benzene is known as aromaticity.

The Chambal River in India forms a radial drainage pattern. The river originates in the Vindhya Range and flows northwards, with its tributaries originating from the surrounding region and converging towards it in a radial pattern.

Insoluble substances are usually neutral because of water being able to stabilize their charged molecules. However, there are some insoluble substances that are not neutral because they still retain their charged molecules.

"as a result" is the correct phrase to use. "As the result" is not grammatically correct.

The subjects required for a Bachelor of Science in Information Technology typically include Mathematics, Computer Science, Physics, and English. Additionally, subjects like Economics and Business Studies may also be beneficial for a well-rounded education in IT.

To pass the wastewater grade 3 exam, study the relevant materials thoroughly, understand key concepts such as treatment processes, regulations, and equipment. Practice with sample questions and past exam papers, and consider taking a prep course if available. On the exam day, manage your time effectively and stay calm while answering the questions.

it was first demonstrated by Sir F.C.Steward.

Since the body is mostly composed of water it is very hard to eliminate fat substances like ether. Certain biological processes besides simple diffusion are needed. Water-soluble substances can be diffused throughout the body used and later eliminated with ease.

Tonometry may be included in an eye examination to measure the intraocular pressure, which can help in diagnosing conditions such as glaucoma.

Please contact your educational institution or check their official website for information regarding the release date of the D.Pharmacy 1st year results.

Hyperpolarization results from an increase in the membrane potential of a cell beyond its resting state, typically caused by an influx of negatively charged ions or an efflux of positively charged ions. This makes the cell less likely to generate an action potential.

The syllabus for the ONGC exam in Chemistry typically includes topics such as Atomic Structure, Periodic Table, Chemical Bonding, Coordination Compounds, Thermodynamics, Chemical Kinetics, Organic Chemistry, and Inorganic Chemistry. It also covers important concepts in Physical Chemistry, Analytical Chemistry, and Environmental Chemistry. Candidates should refer to the official ONGC website for the most updated and detailed syllabus.

Rechecking ded paper involves reviewing the document for errors or missing information. This process includes verifying calculations, checking for spelling or grammatical mistakes, confirming references, and ensuring that the content aligns with the guidelines or requirements provided. It is important to carefully go through the paper to identify and address any issues before final submission.

The contents of a triple science chemistry exam may vary depending on the syllabus or curriculum followed by the educational institution. However, common topics covered in triple science chemistry exams include atomic structure, chemical bonding, chemical reactions, organic chemistry, acids and bases, and the periodic table. Students may also be tested on practical skills like data analysis and experimental techniques.
