Of the choices below, choose the LARGEST set that contains ONLY sp2 hybridized atoms? H₂C 10 11 CH₂ 15 H 5,9, 19 5, 7, 12, 14 5.7. 12, 14 and 19 1, 5, 7, 12, 14 and 19 N. 14 O H₂C 13 17 16 C H 20169 18 'OH 21 Question 10 ( What question in protein folding did Pauling's discovery of secondary structure address? Both alpha-helices and beta-sheets are very stable structures because of the phi-psi conformation of peptide main chain. Alpha-helices and beta-sheets are often the first structures formed in protein folding, and they act as the folding nucleus. O Alpha-helices and beta-sheets show how a folded protein can satisfy the polar groups of the peptide main chain through hydrogen bonding.

Please draw the structure of psylocibin (C12H17N2O4P), with its hybridization and bond angles.

Can you solve the question in the picture shown?

Question (i) is continuation to the previous question

Please help

What are the bond angles around heteroatoms and non-sp3 hybridised C atoms in C14H23NO ?

4. Which of the following molecules will rotate the plane of polarization of plane-polarized light? 1.04 = || = Holla HO OH IV a V

HO: a :N CH3 -c=C-CH2 CH2 H3C Determine the hybridization and the approximate bond angles around the labeled atoms in this structure.

Oxygenated hydrocarbons (compounds containing carbón, hydrogen, and oxygen) are common components of biofuels. The combustion of three isomers of C3H,0 (shown below) were studied to investigate the effects of structure on combustion speed and efficiency (Fuel 2010, 89, 2864-2872). Identify the number of sp3-hybridized carbon atoms in each of these isomers. Structure The number of sp3-hybridized carbon atoms (CH3)2CO HaCHOH CH3CH2CHO

Can you please check if the skeletal and Lewis structure are correct as well as the hybridization. Can you also explain the bonding interactions between each pair of adjacent C atoms?
