Aside from hydrogen, there are also atoms who do not strictly follow the octet rule such as those with expanded octet, incomplete octet, and odd-electron molecules. Significance of Octet Rule. View Answer. View Answer. C 2 H 4. Molecules that do not follow the octet rule are usually more reactive than ones that do. Carbonate can satisfy the octet rule if all of the electrons happen to be shared equally by the carbon and thus filling it's valance shell. A. NCl 3. Which one of the following does not follow octet rule? Exceptions to the Octet Rule. B. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. Which one of the following compounds does not follow the octet rule? Which of the following molecules do not follow the octet rule? According to the octet rule, the atoms of the prime-group elements seem to bind in such a manner that each atom exhibit eight electrons in its valence shell, providing it the similar electronic configuration as a noble gas. Three cases can be constructed that do not follow the Octet Rule, and as such, they are known as the exceptions to the Octet Rule. These electrons are less stable and do not obey the octet rule. View Answer. I hope this helped. I am not … MEDIUM bits. . But this does not happen often since oxygen is much more electronegative and will hold those electrons closer to it most of the time meaning it does no always satisfy the octet rule. Biology. MEDIUM. . The octet rule is not universal although it is useful. The octet rule is not followed by: MEDIUM. Octet rule which can explain the chemical bonding in different compounds. Which of the following does not follow the octet rule ? View Answer. Books. I know I can eliminate E because the total amount of valence electrons in HCl is 8. The octet rule is not valid for which of the following molecules? There are three violations to the octet rule. A) water, H2O B) NO C) carbon dioxide, CO2 D) carbon monoxide, CO E) phosphorous pentachloride, PCl5. C. CS 2. Three cases can be constructed that do not follow the octet rule, and as such, they are known as the exceptions to the octet rule. Free radicals do not follow the octet rule. Octet rules illustrate the different types of bonds, such as a covalent, electrovalent and coordinated bond. Chapter 10 Chemical Bonding I: Basic Concepts NCERT P Bahadur IIT-JEE Previous Year Narendra Awasthi MS Chauhan. D. SBr 4 represent the first violation to the octet rule. View Answer. This does not mean that the octet rule is useless—quite the contrary. Which of the following does not follow the octet rule ? a) NF3 b) CF4 c) SF4 d) PH3 e) HCl I know I can eliminate A and B because nitrogen and carbon follow the octet rule. Answer and Explanation: View Answer. Odd-electron molecules A molecule with an odd number of electrons in the valence shell of an atom. This law is known as the Octet rule. Following the Octet Rule for Lewis Dot Structures leads to the most accurate depictions of stable molecular and atomic structures and because of this we always want to use the octet rule when drawing Lewis Dot Structures. Chemistry. Physics. e (e) As HCN does not follow the octet rule and is mentioned in the above options, option(e) is not the correct answer. As with many rules, there are exceptions, or violations. Limitations of Octet Rule in Points. They have at least one unpaired electron. Many elements do not follow the octet rule. Some of the exceptions about octet rule are given below: An electron or molecule which contains unpaired electrons in its outermost shell or valence shell is considered as free radical.
