CH3 is a trigonal planar and has a hybridization of sp3
acute
It depends whether you mean 3 is an angle or not And if it is it is 90 + 180 + 3=273.
It is an exterior angle and an interior angle plus an exterior angle add up to 180 degrees
1 plus 2 is equal to 3
In mathematics, an obtuse angle is defined as an angle greater than 90° and less than 180°. A right angle is 90°. An acute angle is greater than 0°, but less than 90°. Therefore, a 90° right angle plus any acute angle will always fulfill the requirements of an obtuse angle.
90, 120, and 180
Sp3 hybridization because of the three Hydrogens coming off of the Nitrogen plus one lone pair of electrons on the Nitrogen to satisfy it's octet rule.
sp^3d^2
It is a trigonal pyramidal. It has four bonds and a bond pair-lone pair-bond pair relationship making it trigonal pyramidal rather than the usual tetrahedral that has four bond pairs.
OH alone would be linear shape AX1E3 bond angle 180o
This carbocation which only has six electrons is isoelectronic with BH3 and is believed to have a similar structure as gaseous molecular BH3, planar with bond angles of 120 0. The hybridisation would be sp2 with and empty p orbital.
