Verified by Toppr. Answer. The expected answer is probably D) NO 2−. Explanation : Both O 2 and HCN also exhibit resonance but they have only one major contributor. CO 2 has two major contributors. To determine if resonance is possible, you draw the Lewis structure and then see if you can put the electrons in different locations. (A)CO 2 ...For resonance, unpaired electrons can be donated to stabilize the positive charge of the sigma complex in the transition state. Stabilizing the intermediate, speeds up the reaction by lowering the activating energy. Inductive electron donation by R groups is an analogous, yet weaker effect than resonance. ... -NO 2, -CF 3 > -COR, -CN, -CO 2 R ...1. SO 3 and H 2 SO 4 (fuming) 2. 3. Sulfuric acid is needed in order for a good electrophile to form. Sulfuric acid protonates nitric acid to form the nitronium ion (water molecule is lost). The nitronium ion is a very good electrophile and is open to attack by benzene. Without sulfuric acid the reaction would not occur. 4.The structure of an organic nitro compound. In organic chemistry, nitro compounds are organic compounds that contain one or more nitro functional groups (−NO 2).The nitro group is one of the most common explosophores (functional group that makes a compound explosive) used globally.

It is one of several nitrogen oxides. NO. 2 is an intermediate in the industrial synthesis of nitric acid, millions of tons of which are produced each year for use primarily in the production of fertilizers. At higher temperatures it is a reddish-brown gas. The resonance structures are drawn with the same bond lengths and angles, and the electrons are distributed in the same way between the atoms. The electrons in a resonance structure participate in more than one covalent bond, and the electron pairs are shared between the atoms in different ways.

When we have an H (or H2) in front of a polyatomic molecule (like CO3, ...The NO2 Lewis structure has a total of 17 valence electrons. It's not common to have an odd number of valence electrons in a Lewis structure. Because of this we'll try to get as close to an octet as we can on the central Nitrogen (N) atom. This will mean that it will only have 7 valence electrons. In the Lewis structure for NO2 the Nitrogen ...-NO2: assume ortho-para attack: COOH NO2 + COOH H NO2 COOH H NO 2 COOH H NO2-H+ COOH + slow fast (d) (e) (f) The most disfavored contributing structure This resonance structure accounts for the selectivity Nitration of benzoic acid Organic Lecture Series 40 Activating-Deactivating • Any resonance effect, such as that of -Any resonance effect-NO 2-CN -SO 2R -SO 2NHR -NHR 2-SH-CHO -COR -NO 2-CN-F -Cl -Br -I -CF 3-Ar-OH -OR-NH 2-SH -SO 2R Resonance differs from the two examples above in that it involves the sharing of electrons between more than two atoms via delocalization .

Video transcript. Here's the general reaction for the nitration of benzene. So we start off with benzene, and to it, you add concentrated nitric and concentrated sulfuric acids. And that puts a nitro group onto your benzene ring, in place of this proton. Let's look at the mechanism for the nitration of benzene.The obtained mutual relation between pEDA($\ce{NO2}$) and pEDA(ring) characteristics documents strong resonance interactions for electron-donating substituents in the para position. The observed substituent effect on the $\sigma$ -electron structure of the nitro group, sEDA( $\ce{NO2}$ ), is significantly greater (∼1.6 times) for meta ...Using curly arrows to relate the resonance forms of benzene-related compounds.
