Log in. Table 1: Bond Angles in Halogenated Methane Compounds of General Formula CH 4 and CX 4 Formula Substituent 1 Substituent 2 Substituent 3 ... Hal and H-C-H bond angles can be seen in Table 5 below Table 5 Average Bond Angles of Each Type in Compounds of General Formula CH 3X The shape of methane. The H-C-H bond angles in ethylene are 117 o whereas the H-C-C bond angles are 112.5 o. 109.5 180 90. So as to minimize repulsion, the molecule adopts a tetrahedral shape, hence bond angle becomes 109.5. with bond angle of 90, the molecule would not be very stable. Add your answer and earn points. The H-O-H bond angle in water is 104 o. Select the correct order of bond angle: This question has multiple correct options. help_outline. So the H-C-H bond angle would be 109.5 The bond angles in ammonia and in water are less than 109.5° because of the stronger repulsion by their lone pairs of electrons. The H—C—H bond angle in methane is the tetrahedral angle, 109.5°. Bonding in Methane, CH 4 We are starting with methane because it is the simplest case which illustrates the sort of processes involved. Question. Methane CH 4 has C atom as the central atom which is bonded to four H atoms and has no lone pairs of electrons. Due to lone pair repulsion, the H - 0 - H angle in H2O will: 109.5 180 90. Join now. methane consists of four bonded pairs, i.e 4 C-H bonds. The H-C-H bond angles in methane are all equal at 109.47 o. Thus, C is  s p 3 -hybridized and has the hybrid orbitals in the tetrahedral shape. 1. You have to look at each 'central' atom individually, the H-C-H has a carbon in the center and if we look at only the carbon it has 4 bond pairs, no lone pairs and hence a tetrahedral structure for the CH3O part, leading to 109.5 degrees. When sp 3 orbitals are formed, they arrange themselves so that they are as far apart as possible. Chemistry Q&A Library 13 What is the approximate value of the H-C-H bond angle in methane, CH Select one: Da 120 Ob. HARD. Nothing changes in terms of the shape when the hydrogen atoms combine with the carbon, and so the methane molecule is also tetrahedral with 109.5° bond angles … This angle is obtained when all four pairs of outer electrons repel each other equally. gudasathvikreddy gudasathvikreddy 07.05.2020 Chemistry Secondary School H c h bond angle in methane is 1 See answer gudasathvikreddy is waiting for your help. As such, the bond angle in one is the same for all. Ask your question. Note that the tetrahedral bond angle of $\ce{\sf{H−C−H}}$ is 109.5°. Join now. Log in. That is a tetrahedral arrangement, with an angle of 109.5°. 13 What is the approximate value of the H-C-H bond angle in methane, CH Select one: Da 120 Ob.
